+    <para>For driver debugging purposes this ioctl allows test
+applications to query the driver about the chips present on the TV
+card. Regular applications must not use it. When you found a chip
+specific bug, please contact the linux-media mailing list (&v4l-ml;)
+so it can be fixed.</para>
+
+    <para>Additionally the Linux kernel must be compiled with the
+<constant>CONFIG_VIDEO_ADV_DEBUG</constant> option to enable this ioctl.</para>
+
+    <para>To query the driver applications must initialize the
+<structfield>match.type</structfield> and
+<structfield>match.addr</structfield> or <structfield>match.name</structfield>
+fields of a &v4l2-dbg-chip-info;
+and call <constant>VIDIOC_DBG_G_CHIP_INFO</constant> with a pointer to
+this structure. On success the driver stores information about the
+selected chip in the <structfield>name</structfield> and
+<structfield>flags</structfield> fields. On failure the structure
+remains unchanged.</para>
+
+    <para>When <structfield>match.type</structfield> is
+<constant>V4L2_CHIP_MATCH_BRIDGE</constant>,
+<structfield>match.addr</structfield> selects the nth bridge 'chip'
+on the TV card. You can enumerate all chips by starting at zero and
+incrementing <structfield>match.addr</structfield> by one until
+<constant>VIDIOC_DBG_G_CHIP_INFO</constant> fails with an &EINVAL;.
+The number zero always selects the bridge chip itself, &eg; the chip
+connected to the PCI or USB bus. Non-zero numbers identify specific
+parts of the bridge chip such as an AC97 register block.</para>
+
+    <para>When <structfield>match.type</structfield> is
+<constant>V4L2_CHIP_MATCH_SUBDEV</constant>,
+<structfield>match.addr</structfield> selects the nth sub-device. This
+allows you to enumerate over all sub-devices.</para>
+
+    <para>On success, the <structfield>name</structfield> field will
+contain a chip name and the <structfield>flags</structfield> field will
+contain <constant>V4L2_CHIP_FL_READABLE</constant> if the driver supports
+reading registers from the device or <constant>V4L2_CHIP_FL_WRITABLE</constant>
+if the driver supports writing registers to the device.</para>
+
+    <para>We recommended the <application>v4l2-dbg</application>

+Frequently asked questions about the sunxi clock system
+=======================================================
+
+This document contains useful bits of information that people tend to ask
+about the sunxi clock system, as well as accompanying ASCII art when adequate.
+
+Q: Why is the main 24MHz oscillator gatable? Wouldn't that break the
+   system?
+
+A: The 24MHz oscillator allows gating to save power. Indeed, if gated
+   carelessly the system would stop functioning, but with the right
+   steps, one can gate it and keep the system running. Consider this
+   simplified suspend example:
+
+   While the system is operational, you would see something like
+
+      24MHz         32kHz
+       |
+      PLL1
+       \
+        \_ CPU Mux
+             |
+           [CPU]
+
+   When you are about to suspend, you switch the CPU Mux to the 32kHz
+   oscillator:
+
+      24Mhz         32kHz
+       |              |
+      PLL1            |
+                     /
+           CPU Mux _/
+             |
+           [CPU]
+
+    Finally you can gate the main oscillator
+
+                    32kHz
+                      |
+                      |
+                     /
+           CPU Mux _/
+             |
+           [CPU]
+
+Q: Were can I learn more about the sunxi clocks?
+
+A: The linux-sunxi wiki contains a page documenting the clock registers,
+   you can find it at
+
+        http://linux-sunxi.org/A10/CCM
+
+   The authoritative source for information at this time is the ccmu driver
+   released by Allwinner, you can find it at

+Allowing or denying all by writing 'a' to devices.allow or devices.deny will
+not be possible once the device cgroups has children.
+
+4.1 Hierarchy (internal implementation)
+
+device cgroups is implemented internally using a behavior (ALLOW, DENY) and a
+list of exceptions.  The internal state is controlled using the same user
+interface to preserve compatibility with the previous whitelist-only
+implementation.  Removal or addition of exceptions that will reduce the access
+to devices will be propagated down the hierarchy.
+For every propagated exception, the effective rules will be re-evaluated based
+on current parent's access rules.

-11. TODO
+11. Memory Pressure
+
+The pressure level notifications can be used to monitor the memory
+allocation cost; based on the pressure, applications can implement
+different strategies of managing their memory resources. The pressure
+levels are defined as following:
+
+The "low" level means that the system is reclaiming memory for new
+allocations. Monitoring this reclaiming activity might be useful for
+maintaining cache level. Upon notification, the program (typically
+"Activity Manager") might analyze vmstat and act in advance (i.e.
+prematurely shutdown unimportant services).
+
+The "medium" level means that the system is experiencing medium memory
+pressure, the system might be making swap, paging out active file caches,
+etc. Upon this event applications may decide to further analyze
+vmstat/zoneinfo/memcg or internal memory usage statistics and free any
+resources that can be easily reconstructed or re-read from a disk.
+
+The "critical" level means that the system is actively thrashing, it is
+about to out of memory (OOM) or even the in-kernel OOM killer is on its
+way to trigger. Applications should do whatever they can to help the
+system. It might be too late to consult with vmstat or any other
+statistics, so it's advisable to take an immediate action.
+
+The events are propagated upward until the event is handled, i.e. the
+events are not pass-through. Here is what this means: for example you have
+three cgroups: A->B->C. Now you set up an event listener on cgroups A, B
+and C, and suppose group C experiences some pressure. In this situation,
+only group C will receive the notification, i.e. groups A and B will not
+receive it. This is done to avoid excessive "broadcasting" of messages,
+which disturbs the system and which is especially bad if we are low on
+memory or thrashing. So, organize the cgroups wisely, or propagate the
+events manually (or, ask us to implement the pass-through events,
+explaining why would you need them.)
+
+The file memory.pressure_level is only used to setup an eventfd. To
+register a notification, an application must:
+
+- create an eventfd using eventfd(2);
+- open memory.pressure_level;
+- write string like "<event_fd> <fd of memory.pressure_level> <level>"
+  to cgroup.event_control.
+
+Application will be notified through eventfd when memory pressure is at
+the specific level (or higher). Read/write operations to
+memory.pressure_level are no implemented.
+
+Test:
+
+   Here is a small script example that makes a new cgroup, sets up a
+   memory limit, sets up a notification in the cgroup and then makes child
+   cgroup experience a critical pressure:
+
+   # cd /sys/fs/cgroup/memory/
+   # mkdir foo
+   # cd foo
+   # cgroup_event_listener memory.pressure_level low &
+   # echo 8000000 > memory.limit_in_bytes
+   # echo 8000000 > memory.memsw.limit_in_bytes
+   # echo $$ > tasks
+   # dd if=/dev/zero | read x
+
+   (Expect a bunch of notifications, and eventually, the oom-killer will
+   trigger.)

+Device Tree Clock bindings for arch-sunxi
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be one of the following:
+	"allwinner,sun4i-osc-clk" - for a gatable oscillator
+	"allwinner,sun4i-pll1-clk" - for the main PLL clock
+	"allwinner,sun4i-cpu-clk" - for the CPU multiplexer clock
+	"allwinner,sun4i-axi-clk" - for the AXI clock
+	"allwinner,sun4i-axi-gates-clk" - for the AXI gates
+	"allwinner,sun4i-ahb-clk" - for the AHB clock
+	"allwinner,sun4i-ahb-gates-clk" - for the AHB gates
+	"allwinner,sun4i-apb0-clk" - for the APB0 clock
+	"allwinner,sun4i-apb0-gates-clk" - for the APB0 gates
+	"allwinner,sun4i-apb1-clk" - for the APB1 clock
+	"allwinner,sun4i-apb1-mux-clk" - for the APB1 clock muxing
+	"allwinner,sun4i-apb1-gates-clk" - for the APB1 gates
+
+Required properties for all clocks:
+- reg : shall be the control register address for the clock.
+- clocks : shall be the input parent clock(s) phandle for the clock
+- #clock-cells : from common clock binding; shall be set to 0 except for
+	"allwinner,sun4i-*-gates-clk" where it shall be set to 1
+
+Additionally, "allwinner,sun4i-*-gates-clk" clocks require:
+- clock-output-names : the corresponding gate names that the clock controls
+
+For example:
+
+osc24M: osc24M@01c20050 {
+	#clock-cells = <0>;
+	compatible = "allwinner,sun4i-osc-clk";
+	reg = <0x01c20050 0x4>;
+	clocks = <&osc24M_fixed>;
+};
+
+pll1: pll1@01c20000 {
+	#clock-cells = <0>;
+	compatible = "allwinner,sun4i-pll1-clk";
+	reg = <0x01c20000 0x4>;
+	clocks = <&osc24M>;
+};
+
+cpu: cpu@01c20054 {
+	#clock-cells = <0>;
+	compatible = "allwinner,sun4i-cpu-clk";
+	reg = <0x01c20054 0x4>;
+	clocks = <&osc32k>, <&osc24M>, <&pll1>;
+};
+
+
+
+Gate clock outputs
+
+The "allwinner,sun4i-*-gates-clk" clocks provide several gatable outputs;
+their corresponding offsets as present on sun4i are listed below. Note that
+some of these gates are not present on sun5i.

+Generic ARM big LITTLE cpufreq driver's DT glue
+-----------------------------------------------
+
+This is DT specific glue layer for generic cpufreq driver for big LITTLE
+systems.
+
+Both required and optional properties listed below must be defined
+under node /cpus/cpu@x. Where x is the first cpu inside a cluster.
+
+FIXME: Cpus should boot in the order specified in DT and all cpus for a cluster
+must be present contiguously. Generic DT driver will check only node 'x' for
+cpu:x.

+- operating-points: Refer to Documentation/devicetree/bindings/power/opp.txt
+  for details
+
+Optional properties:
+- clock-latency: Specify the possible maximum transition latency for clock,
+  in unit of nanoseconds.

+This binding is derived from clock bindings, and based on suggestions
+from Lars-Peter Clausen [1].
+
+Sources of IIO channels can be represented by any node in the device
+tree. Those nodes are designated as IIO providers. IIO consumer
+nodes use a phandle and IIO specifier pair to connect IIO provider
+outputs to IIO inputs. Similar to the gpio specifiers, an IIO
+specifier is an array of one or more cells identifying the IIO
+output on a device. The length of an IIO specifier is defined by the
+value of a #io-channel-cells property in the IIO provider node.
+
+[1] http://marc.info/?l=linux-iio&m=135902119507483&w=2
+
+==IIO providers==
+
+Required properties:
+#io-channel-cells: Number of cells in an IIO specifier; Typically 0 for nodes
+		   with a single IIO output and 1 for nodes with multiple
+		   IIO outputs.
+
+Example for a simple configuration with no trigger:
+
+	adc: voltage-sensor@35 {
+		compatible = "maxim,max1139";
+		reg = <0x35>;
+		#io-channel-cells = <1>;
+	};
+
+Example for a configuration with trigger:
+
+	adc@35 {
+		compatible = "some-vendor,some-adc";
+		reg = <0x35>;
+
+		adc1: iio-device@0 {
+			#io-channel-cells = <1>;
+			/* other properties */
+		};
+		adc2: iio-device@1 {
+			#io-channel-cells = <1>;
+			/* other properties */
+		};
+	};
+
+==IIO consumers==
+
+Required properties:
+io-channels:	List of phandle and IIO specifier pairs, one pair
+		for each IIO input to the device. Note: if the
+		IIO provider specifies '0' for #io-channel-cells,
+		then only the phandle portion of the pair will appear.
+
+Optional properties:
+io-channel-names:
+		List of IIO input name strings sorted in the same
+		order as the io-channels property. Consumers drivers
+		will use io-channel-names to match IIO input names
+		with IIO specifiers.
+io-channel-ranges:
+		Empty property indicating that child nodes can inherit named
+		IIO channels from this node. Useful for bus nodes to provide
+		and IIO channel to their children.
+
+For example:
+
+	device {
+		io-channels = <&adc 1>, <&ref 0>;
+		io-channel-names = "vcc", "vdd";
+	};
+
+This represents a device with two IIO inputs, named "vcc" and "vdd".
+The vcc channel is connected to output 1 of the &adc device, and the
+vdd channel is connected to output 0 of the &ref device.
+
+==Example==
+
+	adc: max1139@35 {
+		compatible = "maxim,max1139";
+		reg = <0x35>;
+		#io-channel-cells = <1>;
+	};

+Samsung S5P/EXYNOS SoC Camera Subsystem (FIMC)
+----------------------------------------------
+
+The S5P/Exynos SoC Camera subsystem comprises of multiple sub-devices
+represented by separate device tree nodes. Currently this includes: FIMC (in
+the S5P SoCs series known as CAMIF), MIPI CSIS, FIMC-LITE and FIMC-IS (ISP).
+
+The sub-subdevices are defined as child nodes of the common 'camera' node which
+also includes common properties of the whole subsystem not really specific to
+any single sub-device, like common camera port pins or the CAMCLK clock outputs
+for external image sensors attached to an SoC.
+
+Common 'camera' node
+--------------------
+
+Required properties:
+
+- compatible	: must be "samsung,fimc", "simple-bus"

+		  the clock-names property;
+- clock-names	: must contain "sclk_cam0", "sclk_cam1", "pxl_async0",
+		  "pxl_async1" entries, matching entries in the clocks property.
+
+The pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt must be used
+to define a required pinctrl state named "default" and optional pinctrl states:
+"idle", "active-a", active-b". These optional states can be used to switch the
+camera port pinmux at runtime. The "idle" state should configure both the camera
+ports A and B into high impedance state, especially the CAMCLK clock output
+should be inactive. For the "active-a" state the camera port A must be activated
+and the port B deactivated and for the state "active-b" it should be the other
+way around.
+
+The 'camera' node must include at least one 'fimc' child node.

+  cell) and the horizontal image offset (second cell). The values are in pixels
+  and default to <2 1> when this property is not present;
+- samsung,mainscaler-ext: a boolean property indicating whether the FIMC IP
+  supports extended image size and has CIEXTEN register;

+
+This node should contain child 'port' nodes specifying active parallel video
+input ports. It includes camera A and camera B inputs. 'reg' property in the
+port nodes specifies data input - 0, 1 indicates input A, B respectively.
+
+Optional properties
+

+		       0 - CAM_A_CLKOUT, 1 - CAM_B_CLKOUT;
+
+Image sensor nodes
+------------------

+Common bindings for video receiver and transmitter interfaces
+
+General concept
+---------------
+
+Video data pipelines usually consist of external devices, e.g. camera sensors,
+controlled over an I2C, SPI or UART bus, and SoC internal IP blocks, including
+video DMA engines and video data processors.
+
+SoC internal blocks are described by DT nodes, placed similarly to other SoC
+blocks.  External devices are represented as child nodes of their respective
+bus controller nodes, e.g. I2C.
+
+Data interfaces on all video devices are described by their child 'port' nodes.
+Configuration of a port depends on other devices participating in the data
+transfer and is described by 'endpoint' subnodes.
+
+device {
+	...
+	ports {
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		port@0 {
+			...
+			endpoint@0 { ... };
+			endpoint@1 { ... };
+		};
+		port@1 { ... };
+	};
+};
+
+If a port can be configured to work with more than one remote device on the same
+bus, an 'endpoint' child node must be provided for each of them.  If more than
+one port is present in a device node or there is more than one endpoint at a
+port, or port node needs to be associated with a selected hardware interface,
+a common scheme using '#address-cells', '#size-cells' and 'reg' properties is
+used.
+
+All 'port' nodes can be grouped under optional 'ports' node, which allows to
+specify #address-cells, #size-cells properties independently for the 'port'
+and 'endpoint' nodes and any child device nodes a device might have.
+
+Two 'endpoint' nodes are linked with each other through their 'remote-endpoint'
+phandles.  An endpoint subnode of a device contains all properties needed for
+configuration of this device for data exchange with other device.  In most
+cases properties at the peer 'endpoint' nodes will be identical, however they
+might need to be different when there is any signal modifications on the bus
+between two devices, e.g. there are logic signal inverters on the lines.
+
+It is allowed for multiple endpoints at a port to be active simultaneously,
+where supported by a device.  For example, in case where a data interface of
+a device is partitioned into multiple data busses, e.g. 16-bit input port
+divided into two separate ITU-R BT.656 8-bit busses.  In such case bus-width
+and data-shift properties can be used to assign physical data lines to each
+endpoint node (logical bus).
+
+
+Required properties
+-------------------
+
+If there is more than one 'port' or more than one 'endpoint' node or 'reg'
+property is present in port and/or endpoint nodes the following properties
+are required in a relevant parent node:
+
+ - #address-cells : number of cells required to define port/endpoint
+		    identifier, should be 1.
+ - #size-cells    : should be zero.
+
+Optional endpoint properties
+----------------------------
+
+- remote-endpoint: phandle to an 'endpoint' subnode of a remote device node.
+- slave-mode: a boolean property indicating that the link is run in slave mode.
+  The default when this property is not specified is master mode. In the slave
+  mode horizontal and vertical synchronization signals are provided to the
+  slave device (data source) by the master device (data sink). In the master
+  mode the data source device is also the source of the synchronization signals.
+- bus-width: number of data lines actively used, valid for the parallel busses.
+- data-shift: on the parallel data busses, if bus-width is used to specify the
+  number of data lines, data-shift can be used to specify which data lines are
+  used, e.g. "bus-width=<8>; data-shift=<2>;" means, that lines 9:2 are used.
+- hsync-active: active state of the HSYNC signal, 0/1 for LOW/HIGH respectively.
+- vsync-active: active state of the VSYNC signal, 0/1 for LOW/HIGH respectively.
+  Note, that if HSYNC and VSYNC polarities are not specified, embedded
+  synchronization may be required, where supported.
+- data-active: similar to HSYNC and VSYNC, specifies data line polarity.
+- field-even-active: field signal level during the even field data transmission.
+- pclk-sample: sample data on rising (1) or falling (0) edge of the pixel clock
+  signal.
+- data-lanes: an array of physical data lane indexes. Position of an entry
+  determines the logical lane number, while the value of an entry indicates
+  physical lane, e.g. for 2-lane MIPI CSI-2 bus we could have
+  "data-lanes = <1 2>;", assuming the clock lane is on hardware lane 0.
+  This property is valid for serial busses only (e.g. MIPI CSI-2).
+- clock-lanes: an array of physical clock lane indexes. Position of an entry
+  determines the logical lane number, while the value of an entry indicates
+  physical lane, e.g. for a MIPI CSI-2 bus we could have "clock-lanes = <0>;",
+  which places the clock lane on hardware lane 0. This property is valid for
+  serial busses only (e.g. MIPI CSI-2). Note that for the MIPI CSI-2 bus this
+  array contains only one entry.
+- clock-noncontinuous: a boolean property to allow MIPI CSI-2 non-continuous
+  clock mode.
+
+
+Example
+-------
+
+The example snippet below describes two data pipelines.  ov772x and imx074 are
+camera sensors with a parallel and serial (MIPI CSI-2) video bus respectively.
+Both sensors are on the I2C control bus corresponding to the i2c0 controller
+node.  ov772x sensor is linked directly to the ceu0 video host interface.
+imx074 is linked to ceu0 through the MIPI CSI-2 receiver (csi2). ceu0 has a
+(single) DMA engine writing captured data to memory.  ceu0 node has a single
+'port' node which may indicate that at any time only one of the following data
+pipelines can be active: ov772x -> ceu0 or imx074 -> csi2 -> ceu0.

+
+Every ST-Ericsson Ux500 SOC consists of both ABx500 and DBx500 physically,
+this is kernel hwmon driver for ABx500.
+
+There are some GPADCs inside ABx500 which are designed for connecting to
+thermal sensors, and there is also a thermal sensor inside ABx500 too, which
+raises interrupt when critical temperature reached.
+
+This abx500 is a common layer which can monitor all of the sensors, every
+specific abx500 chip has its special configurations in its own file, e.g. some
+sensors can be configured invisible if they are not available on that chip, and
+the corresponding gpadc_addr should be set to 0, thus this sensor won't be
+polled.

-The ADT7410 is a temperature sensor with rated temperature range of -55°C to
-+150°C. It has a high accuracy of +/-0.5°C and can be operated at a resolution
-of 13 bits (0.0625°C) or 16 bits (0.0078°C). The sensor provides an INT pin to
-indicate that a minimum or maximum temperature set point has been exceeded, as
-well as a critical temperature (CT) pin to indicate that the critical
-temperature set point has been exceeded. Both pins can be set up with a common
-hysteresis of 0°C - 15°C and a fault queue, ranging from 1 to 4 events. Both
-pins can individually set to be active-low or active-high, while the whole
-device can either run in comparator mode or interrupt mode. The ADT7410
-supports continous temperature sampling, as well as sampling one temperature
-value per second or even justget one sample on demand for power saving.
-Besides, it can completely power down its ADC, if power management is
-required.

+Description
+-----------
+
+LM95234 is an 11-bit digital temperature sensor with a 2-wire System Management
+Bus (SMBus) interface and TrueTherm technology that can very accurately monitor
+the temperature of four remote diodes as well as its own temperature.
+The four remote diodes can be external devices such as microprocessors,
+graphics processors or diode-connected 2N3904s. The LM95234's TruTherm
+beta compensation technology allows sensing of 90 nm or 65 nm process
+thermal diodes accurately.
+
+All temperature values are given in millidegrees Celsius. Temperature
+is provided within a range of -127 to +255 degrees (+127.875 degrees for
+the internal sensor). Resolution depends on temperature input and range.
+
+Each sensor has its own maximum limit, but the hysteresis is common to all
+channels. The hysteresis is configurable with the tem1_max_hyst attribute and
+affects the hysteresis on all channels. The first two external sensors also
+have a critical limit.
+
+The lm95234 driver can change its update interval to a fixed set of values.
+It will round up to the next selectable interval. See the datasheet for exact
+values. Reading sensor values more often will do no harm, but will return
+'old' values.

+
+Description
+-----------
+
+This driver implements support for the Nuvoton NCT6775F, NCT6776F, and NCT6779D
+and compatible super I/O chips.
+
+The chips support up to 25 temperature monitoring sources. Up to 6 of those are
+direct temperature sensor inputs, the others are special sources such as PECI,
+PCH, and SMBUS. Depending on the chip type, 2 to 6 of the temperature sources
+can be monitored and compared against minimum, maximum, and critical
+temperatures. The driver reports up to 10 of the temperatures to the user.
+There are 4 to 5 fan rotation speed sensors, 8 to 15 analog voltage sensors,
+one VID, alarms with beep warnings (control unimplemented), and some automatic
+fan regulation strategies (plus manual fan control mode).
+
+The temperature sensor sources on all chips are configurable. The configured
+source for each of the temperature sensors is provided in tempX_label.
+
+Temperatures are measured in degrees Celsius and measurement resolution is
+either 1 degC or 0.5 degC, depending on the temperature source and
+configuration. An alarm is triggered when the temperature gets higher than
+the high limit; it stays on until the temperature falls below the hysteresis
+value. Alarms are only supported for temp1 to temp6, depending on the chip type.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. On
+NCT6775F, fan readings can be divided by a programmable divider (1, 2, 4, 8,
+16, 32, 64 or 128) to give the readings more range or accuracy; the other chips
+do not have a fan speed divider. The driver sets the most suitable fan divisor
+itself; specifically, it increases the divider value each time a fan speed
+reading returns an invalid value, and it reduces it if the fan speed reading
+is lower than optimal. Some fans might not be present because they share pins
+with other functions.
+
+Voltage sensors (also known as IN sensors) report their values in millivolts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit.
+
+The driver supports automatic fan control mode known as Thermal Cruise.
+In this mode, the chip attempts to keep the measured temperature in a
+predefined temperature range. If the temperature goes out of range, fan
+is driven slower/faster to reach the predefined range again.
+
+The mode works for fan1-fan5.
+
+sysfs attributes
+----------------
+
+pwm[1-5] - this file stores PWM duty cycle or DC value (fan speed) in range:
+	   0 (lowest speed) to 255 (full)
+
+pwm[1-5]_enable - this file controls mode of fan/temperature control:
+	* 0 Fan control disabled (fans set to maximum speed)
+	* 1 Manual mode, write to pwm[0-5] any value 0-255
+	* 2 "Thermal Cruise" mode
+	* 3 "Fan Speed Cruise" mode
+	* 4 "Smart Fan III" mode (NCT6775F only)
+	* 5 "Smart Fan IV" mode
+
+pwm[1-5]_mode - controls if output is PWM or DC level
+        * 0 DC output
+        * 1 PWM output
+
+Common fan control attributes
+-----------------------------
+
+pwm[1-5]_temp_sel	Temperature source. Value is temperature sensor index.
+			For example, select '1' for temp1_input.
+pwm[1-5]_weight_temp_sel
+			Secondary temperature source. Value is temperature
+			sensor index. For example, select '1' for temp1_input.
+			Set to 0 to disable secondary temperature control.
+
+If secondary temperature functionality is enabled, it is controlled with the
+following attributes.
+
+pwm[1-5]_weight_duty_step
+			Duty step size.
+pwm[1-5]_weight_temp_step
+			Temperature step size. With each step over
+			temp_step_base, the value of weight_duty_step is added
+			to the current pwm value.
+pwm[1-5]_weight_temp_step_base
+			Temperature at which secondary temperature control kicks
+			in.
+pwm[1-5]_weight_temp_step_tol
+			Temperature step tolerance.
+
+Thermal Cruise mode (2)
+-----------------------
+
+If the temperature is in the range defined by:
+
+pwm[1-5]_target_temp	Target temperature, unit millidegree Celsius
+			(range 0 - 127000)
+pwm[1-5]_temp_tolerance
+			Target temperature tolerance, unit millidegree Celsius
+
+there are no changes to fan speed. Once the temperature leaves the interval, fan
+speed increases (if temperature is higher that desired) or decreases (if
+temperature is lower than desired), using the following limits and time
+intervals.
+
+pwm[1-5]_start		fan pwm start value (range 1 - 255), to start fan
+			when the temperature is above defined range.
+pwm[1-5]_floor		lowest fan pwm (range 0 - 255) if temperature is below
+			the defined range. If set to 0, the fan is expected to
+			stop if the temperature is below the defined range.
+pwm[1-5]_step_up_time	milliseconds before fan speed is increased
+pwm[1-5]_step_down_time	milliseconds before fan speed is decreased
+pwm[1-5]_stop_time	how many milliseconds must elapse to switch
+			corresponding fan off (when the temperature was below
+			defined range).
+
+Speed Cruise mode (3)
+---------------------
+
+This modes tries to keep the fan speed constant.
+
+fan[1-5]_target		Target fan speed
+fan[1-5]_tolerance
+			Target speed tolerance
+
+
+Untested; use at your own risk.
+
+Smart Fan IV mode (5)
+---------------------
+
+This mode offers multiple slopes to control the fan speed. The slopes can be
+controlled by setting the pwm and temperature attributes. When the temperature
+rises, the chip will calculate the DC/PWM output based on the current slope.
+There are up to seven data points depending on the chip type. Subsequent data
+points should be set to higher temperatures and higher pwm values to achieve
+higher fan speeds with increasing temperature. The last data point reflects
+critical temperature mode, in which the fans should run at full speed.
+
+pwm[1-5]_auto_point[1-7]_pwm
+			pwm value to be set if temperature reaches matching
+			temperature range.
+pwm[1-5]_auto_point[1-7]_temp
+			Temperature over which the matching pwm is enabled.
+pwm[1-5]_temp_tolerance
+			Temperature tolerance, unit millidegree Celsius
+pwm[1-5]_crit_temp_tolerance
+			Temperature tolerance for critical temperature,
+			unit millidegree Celsius
+
+pwm[1-5]_step_up_time	milliseconds before fan speed is increased
+pwm[1-5]_step_down_time	milliseconds before fan speed is decreased
+
+Usage Notes
+-----------
+
+On various ASUS boards with NCT6776F, it appears that CPUTIN is not really
+connected to anything and floats, or that it is connected to some non-standard
+temperature measurement device. As a result, the temperature reported on CPUTIN
+will not reflect a usable value. It often reports unreasonably high
+temperatures, and in some cases the reported temperature declines if the actual
+temperature increases (similar to the raw PECI temperature value - see PECI
+specification for details). CPUTIN should therefore be be ignored on ASUS
+boards. The CPU temperature on ASUS boards is reported from PECI 0.

+Intel(R) Management Engine (ME) Client bus API
+===============================================
+
+
+Rationale
+=========
+MEI misc character device is useful for dedicated applications to send and receive
+data to the many FW appliance found in Intel's ME from the user space.
+However for some of the ME functionalities it make sense to leverage existing software
+stack and expose them through existing kernel subsystems.
+
+In order to plug seamlessly into the kernel device driver model we add kernel virtual
+bus abstraction on top of the MEI driver. This allows implementing linux kernel drivers
+for the various MEI features as a stand alone entities found in their respective subsystem.
+Existing device drivers can even potentially be re-used by adding an MEI CL bus layer to
+the existing code.
+
+
+MEI CL bus API
+===========
+A driver implementation for an MEI Client is very similar to existing bus
+based device drivers. The driver registers itself as an MEI CL bus driver through
+the mei_cl_driver structure:
+
+struct mei_cl_driver {
+	struct device_driver driver;
+	const char *name;
+
+	const struct mei_cl_device_id *id_table;
+
+	int (*probe)(struct mei_cl_device *dev, const struct mei_cl_id *id);
+	int (*remove)(struct mei_cl_device *dev);
+};
+
+struct mei_cl_id {
+	char name[MEI_NAME_SIZE];
+	kernel_ulong_t driver_info;
+};
+
+The mei_cl_id structure allows the driver to bind itself against a device name.
+
+To actually register a driver on the ME Client bus one must call the mei_cl_add_driver()
+API. This is typically called at module init time.
+
+Once registered on the ME Client bus, a driver will typically try to do some I/O on
+this bus and this should be done through the mei_cl_send() and mei_cl_recv()
+routines. The latter is synchronous (blocks and sleeps until data shows up).
+In order for drivers to be notified of pending events waiting for them (e.g.
+an Rx event) they can register an event handler through the
+mei_cl_register_event_cb() routine. Currently only the MEI_EVENT_RX event
+will trigger an event handler call and the driver implementation is supposed
+to call mei_recv() from the event handler in order to fetch the pending
+received buffers.
+
+
+Example
+=======
+As a theoretical example let's pretend the ME comes with a "contact" NFC IP.
+The driver init and exit routines for this device would look like:
+
+#define CONTACT_DRIVER_NAME "contact"
+
+static struct mei_cl_device_id contact_mei_cl_tbl[] = {
+	{ CONTACT_DRIVER_NAME, },
+
+	/* required last entry */
+	{ }
+};
+MODULE_DEVICE_TABLE(mei_cl, contact_mei_cl_tbl);
+
+static struct mei_cl_driver contact_driver = {
+       .id_table = contact_mei_tbl,
+       .name = CONTACT_DRIVER_NAME,
+
+       .probe = contact_probe,
+       .remove = contact_remove,
+};
+
+static int contact_init(void)
+{
+	int r;
+
+	r = mei_cl_driver_register(&contact_driver);
+	if (r) {
+		pr_err(CONTACT_DRIVER_NAME ": driver registration failed\n");
+		return r;
+	}
+
+	return 0;
+}
+
+static void __exit contact_exit(void)
+{
+	mei_cl_driver_unregister(&contact_driver);
+}
+
+module_init(contact_init);
+module_exit(contact_exit);
+
+And the driver's simplified probe routine would look like that:
+
+int contact_probe(struct mei_cl_device *dev, struct mei_cl_device_id *id)
+{
+	struct contact_driver *contact;
+
+	[...]
+	mei_cl_enable_device(dev);
+
+	mei_cl_register_event_cb(dev, contact_event_cb, contact);
+
+	return 0;
+ }
+
+In the probe routine the driver first enable the MEI device and then registers
+an ME bus event handler which is as close as it can get to registering a
+threaded IRQ handler.
+The handler implementation will typically call some I/O routine depending on
+the pending events:
+
+#define MAX_NFC_PAYLOAD 128
+
+static void contact_event_cb(struct mei_cl_device *dev, u32 events,
+			     void *context)
+{
+	struct contact_driver *contact = context;
+
+	if (events & BIT(MEI_EVENT_RX)) {
+		u8 payload[MAX_NFC_PAYLOAD];
+		int payload_size;
+
+		payload_size = mei_recv(dev, payload, MAX_NFC_PAYLOAD);
+		if (payload_size <= 0)
+			return;
+
+		/* Hook to the NFC subsystem */
+		nfc_hci_recv_frame(contact->hdev, payload, payload_size);
+	}
+}

+GPIO mode pitfalls
+==================
+
+Sometime the developer may be confused by a datasheet talking about a pin
+being possible to set into "GPIO mode". It appears that what hardware
+engineers mean with "GPIO mode" is not necessarily the use case that is
+implied in the kernel interface <linux/gpio.h>: a pin that you grab from
+kernel code and then either listen for input or drive high/low to
+assert/deassert some external line.
+
+Rather hardware engineers think that "GPIO mode" means that you can
+software-control a few electrical properties of the pin that you would
+not be able to control if the pin was in some other mode, such as muxed in
+for a device.
+
+Example: a pin is usually muxed in to be used as a UART TX line. But during
+system sleep, we need to put this pin into "GPIO mode" and ground it.
+
+If you make a 1-to-1 map to the GPIO subsystem for this pin, you may start
+to think that you need to come up with something real complex, that the
+pin shall be used for UART TX and GPIO at the same time, that you will grab
+a pin control handle and set it to a certain state to enable UART TX to be
+muxed in, then twist it over to GPIO mode and use gpio_direction_output()
+to drive it low during sleep, then mux it over to UART TX again when you
+wake up and maybe even gpio_request/gpio_free as part of this cycle. This
+all gets very complicated.
+
+The solution is to not think that what the datasheet calls "GPIO mode"
+has to be handled by the <linux/gpio.h> interface. Instead view this as
+a certain pin config setting. Look in e.g. <linux/pinctrl/pinconf-generic.h>
+and you find this in the documentation:
+
+  PIN_CONFIG_OUTPUT: this will configure the pin in output, use argument
+     1 to indicate high level, argument 0 to indicate low level.
+
+So it is perfectly possible to push a pin into "GPIO mode" and drive the
+line low as part of the usual pin control map. So for example your UART
+driver may look like this:
+
+#include <linux/pinctrl/consumer.h>
+
+struct pinctrl          *pinctrl;
+struct pinctrl_state    *pins_default;
+struct pinctrl_state    *pins_sleep;
+
+pins_default = pinctrl_lookup_state(uap->pinctrl, PINCTRL_STATE_DEFAULT);
+pins_sleep = pinctrl_lookup_state(uap->pinctrl, PINCTRL_STATE_SLEEP);
+
+/* Normal mode */
+retval = pinctrl_select_state(pinctrl, pins_default);
+/* Sleep mode */
+retval = pinctrl_select_state(pinctrl, pins_sleep);
+
+And your machine configuration may look like this:
+--------------------------------------------------
+
+static unsigned long uart_default_mode[] = {
+    PIN_CONF_PACKED(PIN_CONFIG_DRIVE_PUSH_PULL, 0),
+};
+
+static unsigned long uart_sleep_mode[] = {
+    PIN_CONF_PACKED(PIN_CONFIG_OUTPUT, 0),
+};
+
+static struct pinctrl_map __initdata pinmap[] = {
+    PIN_MAP_MUX_GROUP("uart", PINCTRL_STATE_DEFAULT, "pinctrl-foo",
+                      "u0_group", "u0"),
+    PIN_MAP_CONFIGS_PIN("uart", PINCTRL_STATE_DEFAULT, "pinctrl-foo",
+                        "UART_TX_PIN", uart_default_mode),
+    PIN_MAP_MUX_GROUP("uart", PINCTRL_STATE_SLEEP, "pinctrl-foo",
+                      "u0_group", "gpio-mode"),
+    PIN_MAP_CONFIGS_PIN("uart", PINCTRL_STATE_SLEEP, "pinctrl-foo",
+                        "UART_TX_PIN", uart_sleep_mode),
+};
+
+foo_init(void) {
+    pinctrl_register_mappings(pinmap, ARRAY_SIZE(pinmap));
+}
+
+Here the pins we want to control are in the "u0_group" and there is some
+function called "u0" that can be enabled on this group of pins, and then
+everything is UART business as usual. But there is also some function
+named "gpio-mode" that can be mapped onto the same pins to move them into
+GPIO mode.
+
+This will give the desired effect without any bogus interaction with the
+GPIO subsystem. It is just an electrical configuration used by that device
+when going to sleep, it might imply that the pin is set into something the
+datasheet calls "GPIO mode" but that is not the point: it is still used
+by that UART device to control the pins that pertain to that very UART
+driver, putting them into modes needed by the UART. GPIO in the Linux
+kernel sense are just some 1-bit line, and is a different use case.
+
+How the registers are poked to attain the push/pull and output low
+configuration and the muxing of the "u0" or "gpio-mode" group onto these
+pins is a question for the driver.
+
+Some datasheets will be more helpful and refer to the "GPIO mode" as
+"low power mode" rather than anything to do with GPIO. This often means
+the same thing electrically speaking, but in this latter case the
+software engineers will usually quickly identify that this is some
+specific muxing/configuration rather than anything related to the GPIO
+API.

+this_cpu operations
+-------------------
+
+this_cpu operations are a way of optimizing access to per cpu
+variables associated with the *currently* executing processor through
+the use of segment registers (or a dedicated register where the cpu
+permanently stored the beginning of the per cpu area for a specific
+processor).
+
+The this_cpu operations add a per cpu variable offset to the processor
+specific percpu base and encode that operation in the instruction
+operating on the per cpu variable.
+
+This means there are no atomicity issues between the calculation of
+the offset and the operation on the data. Therefore it is not
+necessary to disable preempt or interrupts to ensure that the
+processor is not changed between the calculation of the address and
+the operation on the data.
+
+Read-modify-write operations are of particular interest. Frequently
+processors have special lower latency instructions that can operate
+without the typical synchronization overhead but still provide some
+sort of relaxed atomicity guarantee. The x86 for example can execute
+RMV (Read Modify Write) instructions like inc/dec/cmpxchg without the
+lock prefix and the associated latency penalty.
+
+Access to the variable without the lock prefix is not synchronized but
+synchronization is not necessary since we are dealing with per cpu
+data specific to the currently executing processor. Only the current
+processor should be accessing that variable and therefore there are no
+concurrency issues with other processors in the system.
+
+On x86 the fs: or the gs: segment registers contain the base of the
+per cpu area. It is then possible to simply use the segment override
+to relocate a per cpu relative address to the proper per cpu area for
+the processor. So the relocation to the per cpu base is encoded in the
+instruction via a segment register prefix.
+
+For example:
+
+	DEFINE_PER_CPU(int, x);
+	int z;
+
+	z = this_cpu_read(x);
+
+results in a single instruction
+
+	mov ax, gs:[x]
+
+instead of a sequence of calculation of the address and then a fetch
+from that address which occurs with the percpu operations. Before
+this_cpu_ops such sequence also required preempt disable/enable to
+prevent the kernel from moving the thread to a different processor
+while the calculation is performed.
+
+The main use of the this_cpu operations has been to optimize counter
+operations.
+
+	this_cpu_inc(x)
+
+results in the following single instruction (no lock prefix!)
+
+	inc gs:[x]
+
+instead of the following operations required if there is no segment
+register.
+
+	int *y;
+	int cpu;
+
+	cpu = get_cpu();
+	y = per_cpu_ptr(&x, cpu);
+	(*y)++;
+	put_cpu();
+
+Note that these operations can only be used on percpu data that is
+reserved for a specific processor. Without disabling preemption in the
+surrounding code this_cpu_inc() will only guarantee that one of the
+percpu counters is correctly incremented. However, there is no
+guarantee that the OS will not move the process directly before or
+after the this_cpu instruction is executed. In general this means that
+the value of the individual counters for each processor are
+meaningless. The sum of all the per cpu counters is the only value
+that is of interest.
+
+Per cpu variables are used for performance reasons. Bouncing cache
+lines can be avoided if multiple processors concurrently go through
+the same code paths.  Since each processor has its own per cpu
+variables no concurrent cacheline updates take place. The price that
+has to be paid for this optimization is the need to add up the per cpu
+counters when the value of the counter is needed.
+
+
+Special operations:
+-------------------
+
+	y = this_cpu_ptr(&x)
+
+Takes the offset of a per cpu variable (&x !) and returns the address
+of the per cpu variable that belongs to the currently executing
+processor.  this_cpu_ptr avoids multiple steps that the common
+get_cpu/put_cpu sequence requires. No processor number is
+available. Instead the offset of the local per cpu area is simply
+added to the percpu offset.
+
+
+
+Per cpu variables and offsets
+-----------------------------
+
+Per cpu variables have *offsets* to the beginning of the percpu
+area. They do not have addresses although they look like that in the
+code. Offsets cannot be directly dereferenced. The offset must be
+added to a base pointer of a percpu area of a processor in order to
+form a valid address.
+
+Therefore the use of x or &x outside of the context of per cpu
+operations is invalid and will generally be treated like a NULL
+pointer dereference.
+
+In the context of per cpu operations
+
+	x is a per cpu variable. Most this_cpu operations take a cpu
+	variable.
+
+	&x is the *offset* a per cpu variable. this_cpu_ptr() takes
+	the offset of a per cpu variable which makes this look a bit
+	strange.
+
+
+
+Operations on a field of a per cpu structure
+--------------------------------------------
+
+Let's say we have a percpu structure
+
+	struct s {
+		int n,m;
+	};
+
+	DEFINE_PER_CPU(struct s, p);
+
+
+Operations on these fields are straightforward
+
+	this_cpu_inc(p.m)
+
+	z = this_cpu_cmpxchg(p.m, 0, 1);
+
+
+If we have an offset to struct s:
+
+	struct s __percpu *ps = &p;
+
+	z = this_cpu_dec(ps->m);
+
+	z = this_cpu_inc_return(ps->n);
+
+
+The calculation of the pointer may require the use of this_cpu_ptr()
+if we do not make use of this_cpu ops later to manipulate fields:
+
+	struct s *pp;
+
+	pp = this_cpu_ptr(&p);
+
+	pp->m--;
+
+	z = pp->n++;
+
+
+Variants of this_cpu ops
+-------------------------
+
+this_cpu ops are interrupt safe. Some architecture do not support
+these per cpu local operations. In that case the operation must be
+replaced by code that disables interrupts, then does the operations
+that are guaranteed to be atomic and then reenable interrupts. Doing
+so is expensive. If there are other reasons why the scheduler cannot
+change the processor we are executing on then there is no reason to
+disable interrupts. For that purpose the __this_cpu operations are
+provided. For example.
+
+	__this_cpu_inc(x);
+
+Will increment x and will not fallback to code that disables
+interrupts on platforms that cannot accomplish atomicity through
+address relocation and a Read-Modify-Write operation in the same
+instruction.
+
+
+
+&this_cpu_ptr(pp)->n vs this_cpu_ptr(&pp->n)
+--------------------------------------------
+
+The first operation takes the offset and forms an address and then
+adds the offset of the n field.
+
+The second one first adds the two offsets and then does the
+relocation.  IMHO the second form looks cleaner and has an easier time
+with (). The second form also is consistent with the way
+this_cpu_read() and friends are used.

+
+	Used with the function graph tracer. This is the max depth

+
+  printk_formats:
+
+	This is for tools that read the raw format files. If an event in
+	the ring buffer references a string (currently only trace_printk()
+	does this), only a pointer to the string is recorded into the buffer
+	and not the string itself. This prevents tools from knowing what
+	that string was. This file displays the string and address for
+	the string allowing tools to map the pointers to what the
+	strings were.
+
+  saved_cmdlines:
+
+	Only the pid of the task is recorded in a trace event unless
+	the event specifically saves the task comm as well. Ftrace
+	makes a cache of pid mappings to comms to try to display
+	comms for events. If a pid for a comm is not listed, then
+	"<...>" is displayed in the output.

+
+  stack_trace_filter:
+
+	This is similar to "set_ftrace_filter" but it limits what
+	functions the stack tracer will check.
+
+  trace_clock:
+
+	Whenever an event is recorded into the ring buffer, a
+	"timestamp" is added. This stamp comes from a specified
+	clock. By default, ftrace uses the "local" clock. This
+	clock is very fast and strictly per cpu, but on some
+	systems it may not be monotonic with respect to other
+	CPUs. In other words, the local clocks may not be in sync
+	with local clocks on other CPUs.
+
+	Usual clocks for tracing:
+
+	  # cat trace_clock
+	  [local] global counter x86-tsc
+
+	  local: Default clock, but may not be in sync across CPUs
+
+	  global: This clock is in sync with all CPUs but may
+	  	  be a bit slower than the local clock.
+
+	  counter: This is not a clock at all, but literally an atomic
+	  	   counter. It counts up one by one, but is in sync
+		   with all CPUs. This is useful when you need to
+		   know exactly the order events occurred with respect to
+		   each other on different CPUs.
+
+	  uptime: This uses the jiffies counter and the time stamp
+	  	  is relative to the time since boot up.
+
+	  perf: This makes ftrace use the same clock that perf uses.
+	  	Eventually perf will be able to read ftrace buffers
+		and this will help out in interleaving the data.
+
+	  x86-tsc: Architectures may define their own clocks. For

+	(also known as static tracepoints) that have been compiled

+	files at various levels that can enable the tracepoints
+	when a "1" is written to them.
+
+	See events.txt for more information.
+
+  per_cpu:
+
+	This is a directory that contains the trace per_cpu information.
+
+  per_cpu/cpu0/buffer_size_kb:
+
+	The ftrace buffer is defined per_cpu. That is, there's a separate
+	buffer for each CPU to allow writes to be done atomically,
+	and free from cache bouncing. These buffers may have different
+	size buffers. This file is similar to the buffer_size_kb
+	file, but it only displays or sets the buffer size for the
+	specific CPU. (here cpu0).
+
+  per_cpu/cpu0/trace:
+
+	This is similar to the "trace" file, but it will only display
+	the data specific for the CPU. If written to, it only clears
+	the specific CPU buffer.
+
+  per_cpu/cpu0/trace_pipe
+
+	This is similar to the "trace_pipe" file, and is a consuming
+	read, but it will only display (and consume) the data specific
+	for the CPU.
+
+  per_cpu/cpu0/trace_pipe_raw
+
+	For tools that can parse the ftrace ring buffer binary format,
+	the trace_pipe_raw file can be used to extract the data
+	from the ring buffer directly. With the use of the splice()
+	system call, the buffer data can be quickly transferred to
+	a file or to the network where a server is collecting the
+	data.
+
+	Like trace_pipe, this is a consuming reader, where multiple
+	reads will always produce different data.
+
+  per_cpu/cpu0/snapshot:
+
+	This is similar to the main "snapshot" file, but will only
+	snapshot the current CPU (if supported). It only displays
+	the content of the snapshot for a given CPU, and if
+	written to, only clears this CPU buffer.
+
+  per_cpu/cpu0/snapshot_raw:
+
+	Similar to the trace_pipe_raw, but will read the binary format
+	from the snapshot buffer for the given CPU.
+
+  per_cpu/cpu0/stats:
+
+	This displays certain stats about the ring buffer:
+
+	 entries: The number of events that are still in the buffer.
+
+	 overrun: The number of lost events due to overwriting when
+	 	  the buffer was full.
+
+	 commit overrun: Should always be zero.
+	 	This gets set if so many events happened within a nested
+		event (ring buffer is re-entrant), that it fills the
+		buffer and starts dropping events.
+
+	 bytes: Bytes actually read (not overwritten).
+
+	 oldest event ts: The oldest timestamp in the buffer
+
+	 now ts: The current timestamp
+
+	 dropped events: Events lost due to overwrite option being off.
+
+	 read events: The number of events read.

+	       When enabled, it will account time the task has been
+	       scheduled out as part of the function call.
+
+  graph-time - When running function graph tracer, to include the
+  	       time to call nested functions. When this is not set,
+	       the time reported for the function will only include
+	       the time the function itself executed for, not the time
+	       for functions that it called.
+
+  record-cmd - When any event or tracer is enabled, a hook is enabled
+  	       in the sched_switch trace point to fill comm cache
+	       with mapped pids and comms. But this may cause some
+	       overhead, and if you only care about pids, and not the
+	       name of the task, disabling this option can lower the
+	       impact of tracing.
+
   overwrite - This controls what happens when the trace buffer is
               full. If "1" (default), the oldest events are
               discarded and overwritten. If "0", then the newest
               events are discarded.
+	        (see per_cpu/cpu0/stats for overrun and dropped)
 
-ftrace_enabled
---------------
+  disable_on_free - When the free_buffer is closed, tracing will
+  		    stop (tracing_on set to 0).
 
-The following tracers (listed below) give different output
-depending on whether or not the sysctl ftrace_enabled is set. To
-set ftrace_enabled, one can either use the sysctl function or
-set it via the proc file system interface.
+  irq-info - Shows the interrupt, preempt count, need resched data.
+  	     When disabled, the trace looks like:
 
-  sysctl kernel.ftrace_enabled=1
+# tracer: function
+#
+# entries-in-buffer/entries-written: 144405/9452052   #P:4

+  markers - When set, the trace_marker is writable (only by root).
+  	    When disabled, the trace_marker will error with EINVAL
+	    on write.
 
-To disable ftrace_enabled simply replace the '1' with '0' in the
-above commands.
 
-When ftrace_enabled is set the tracers will also record the
-functions that are within the trace. The descriptions of the
-tracers will also show an example with ftrace enabled.
+  function-trace - The latency tracers will enable function tracing
+  	    if this option is enabled (default it is). When
+	    it is disabled, the latency tracers do not trace
+	    functions. This keeps the overhead of the tracer down
+	    when performing latency tests.
+
+ Note: Some tracers have their own options. They only appear
+       when the tracer is active.

 The above is an example of the preemptoff trace with
-ftrace_enabled set. Here we see that interrupts were disabled
+function-trace set. Here we see that interrupts were not disabled
 the entire time. The irq_enter code lets us know that we entered
 an interrupt 'h'. Before that, the functions being traced still
 show that it is not in an interrupt, but we can see from the
 functions themselves that this is not the case.
 
-Notice that __do_softirq when called does not have a
-preempt_count. It may seem that we missed a preempt enabling.
-What really happened is that the preempt count is held on the
-thread's stack and we switched to the softirq stack (4K stacks
-in effect). The code does not copy the preempt count, but
-because interrupts are disabled, we do not need to worry about
-it. Having a tracer like this is good for letting people know
-what really happens inside the kernel.

-This is a very interesting trace. It started with the preemption
-of the ls task. We see that the task had the "need_resched" bit
-set via the 'N' in the trace.  Interrupts were disabled before
-the spin_lock at the beginning of the trace. We see that a
-schedule took place to run sshd.  When the interrupts were
-enabled, we took an interrupt. On return from the interrupt
-handler, the softirq ran. We took another interrupt while
-running the softirq as we see from the capital 'H'.
+This is an interesting trace. It started with kworker running and
+scheduling out and ls taking over. But as soon as ls released the
+rq lock and enabled interrupts (but not preemption) an interrupt
+triggered. When the interrupt finished, it started running softirqs.
+But while the softirq was running, another interrupt triggered.
+When an interrupt is running inside a softirq, the annotation is 'H'.
 
 
 wakeup
 ------
 
+One common case that people are interested in tracing is the
+time it takes for a task that is woken to actually wake up.
+Now for non Real-Time tasks, this can be arbitrary. But tracing
+it none the less can be interesting.

+The tracer only traces the highest priority task in the system
+to avoid tracing the normal circumstances. Here we see that
+the kworker with a nice priority of -20 (not very nice), took
+just 15 microseconds from the time it woke up, to the time it
+ran.
+
+Non Real-Time tasks are not that interesting. A more interesting
+trace is to concentrate only on Real-Time tasks.

 Since this tracer only deals with RT tasks, we will run this
 slightly differently than we did with the previous tracers.
 Instead of performing an 'ls', we will run 'sleep 1' under
 'chrt' which changes the priority of the task.

-The interrupt went off while running ksoftirqd. This task runs
-at SCHED_OTHER. Why did not we see the 'N' set early? This may
-be a harmless bug with x86_32 and 4K stacks. On x86_32 with 4K
-stacks configured, the interrupt and softirq run with their own
-stack. Some information is held on the top of the task's stack
-(need_resched and preempt_count are both stored there). The
-setting of the NEED_RESCHED bit is done directly to the task's
-stack, but the reading of the NEED_RESCHED is done by looking at
-the current stack, which in this case is the stack for the hard
-interrupt. This hides the fact that NEED_RESCHED has been set.
-We do not see the 'N' until we switch back to the task's
-assigned stack.
+The interrupt went off while when the system was idle. Somewhere
+before task_woken_rt() was called, the NEED_RESCHED flag was set,
+this is indicated by the first occurrence of the 'N' flag.

+Latency tracing and events
+--------------------------
+As function tracing can induce a much larger latency, but without
+seeing what happens within the latency it is hard to know what
+caused it. There is a middle ground, and that is with enabling
+events.

+--------------
+
+Note, the proc sysctl ftrace_enable is a big on/off switch for the
+function tracer. By default it is enabled (when function tracing is
+enabled in the kernel). If it is disabled, all function tracing is
+disabled. This includes not only the function tracers for ftrace, but
+also for any other uses (perf, kprobes, stack tracing, profiling, etc).
+
+Please disable this with care.
+
+This can be disable (and enabled) with:

+  sysctl kernel.ftrace_enabled=0

+Instances
+---------
+In the debugfs tracing directory is a directory called "instances".
+This directory can have new directories created inside of it using
+mkdir, and removing directories with rmdir. The directory created
+with mkdir in this directory will already contain files and other
+directories after it is created.

+set_event  snapshot  trace  trace_clock  trace_marker  trace_options
+trace_pipe  tracing_on
+
+As you can see, the new directory looks similar to the tracing directory
+itself. In fact, it is very similar, except that the buffer and
+events are agnostic from the main director, or from any other
+instances that are created.
+
+The files in the new directory work just like the files with the
+same name in the tracing directory except the buffer that is used
+is a separate and new buffer. The files affect that buffer but do not
+affect the main buffer with the exception of trace_options. Currently,
+the trace_options affect all instances and the top level buffer
+the same, but this may change in future releases. That is, options
+may become specific to the instance they reside in.
+
+Notice that none of the function tracer files are there, nor is
+current_tracer and available_tracers. This is because the buffers
+can currently only have events enabled for them.

+You can see that the trace of the top most trace buffer shows only
+the function tracing. The foo instance displays wakeups and task
+switches.
+
+To remove the instances, simply delete their directories:
+
+ # rmdir instances/foo
+ # rmdir instances/bar
+ # rmdir instances/zoot
+
+Note, if a process has a trace file open in one of the instance
+directories, the rmdir will fail with EBUSY.
+
+
+Stack trace
 -----------
+Since the kernel has a fixed sized stack, it is important not to
+waste it in functions. A kernel developer must be conscience of
+what they allocate on the stack. If they add too much, the system
+can be in danger of a stack overflow, and corruption will occur,
+usually leading to a system panic.
+
+There are some tools that check this, usually with interrupts
+periodically checking usage. But if you can perform a check
+at every function call that will become very useful. As ftrace provides
+a function tracer, it makes it convenient to check the stack size
+at every function call. This is enabled via the stack tracer.
+
+CONFIG_STACK_TRACER enables the ftrace stack tracing functionality.
+To enable it, write a '1' into /proc/sys/kernel/stack_tracer_enabled.
+
+ # echo 1 > /proc/sys/kernel/stack_tracer_enabled
+
+You can also enable it from the kernel command line to trace
+the stack size of the kernel during boot up, by adding "stacktrace"
+to the kernel command line parameter.
+
+After running it for a few minutes, the output looks like:
+
+ # cat stack_max_size
+2928
+
+ # cat stack_trace

+Note, if -mfentry is being used by gcc, functions get traced before
+they set up the stack frame. This means that leaf level functions

 Usage examples
 --------------
-To add a probe as a new event, write a new definition to uprobe_events
-as below.
+ * Add a probe as a new uprobe event, write a new definition to uprobe_events
+as below: (sets a uprobe at an offset of 0x4245c0 in the executable /bin/bash)
 
-  echo 'p: /bin/bash:0x4245c0' > /sys/kernel/debug/tracing/uprobe_events
+    echo 'p: /bin/bash:0x4245c0' > /sys/kernel/debug/tracing/uprobe_events
 
- This sets a uprobe at an offset of 0x4245c0 in the executable /bin/bash
+ * Add a probe as a new uretprobe event:
 
-  echo > /sys/kernel/debug/tracing/uprobe_events
+    echo 'r: /bin/bash:0x4245c0' > /sys/kernel/debug/tracing/uprobe_events
 
- This clears all probe points.
+ * Unset registered event:
 
-The following example shows how to dump the instruction pointer and %ax
-a register at the probed text address.  Here we are trying to probe
-function zfree in /bin/zsh
+    echo '-:bash_0x4245c0' >> /sys/kernel/debug/tracing/uprobe_events
+
+ * Print out the events that are registered:
+
+    cat /sys/kernel/debug/tracing/uprobe_events
+
+ * Clear all events:
+
+    echo > /sys/kernel/debug/tracing/uprobe_events
+
+Following example shows how to dump the instruction pointer and %ax register
+at the probed text address. Probe zfree function in /bin/zsh:
 
     # cd /sys/kernel/debug/tracing/
-    # cat /proc/`pgrep  zsh`/maps | grep /bin/zsh | grep r-xp
+    # cat /proc/`pgrep zsh`/maps | grep /bin/zsh | grep r-xp
     00400000-0048a000 r-xp 00000000 08:03 130904 /bin/zsh
     # objdump -T /bin/zsh | grep -w zfree
     0000000000446420 g    DF .text  0000000000000012  Base        zfree
 
-0x46420 is the offset of zfree in object /bin/zsh that is loaded at
-0x00400000. Hence the command to probe would be :
+  0x46420 is the offset of zfree in object /bin/zsh that is loaded at

+    # echo 'p:zfree_entry /bin/zsh:0x46420 %ip %ax' > uprobe_events
 
-Please note: User has to explicitly calculate the offset of the probepoint
+  And the same for the uretprobe would be:
+
+    # echo 'r:zfree_exit /bin/zsh:0x46420 %ip %ax' >> uprobe_events
+
+Please note: User has to explicitly calculate the offset of the probe-point
 in the object. We can see the events that are registered by looking at the

+SI476x Driver Readme
+------------------------------------------------
+	Copyright (C) 2013 Andrey Smirnov <andrew.smirnov@gmail.com>
+
+TODO for the driver
+------------------------------
+
+- According to the SiLabs' datasheet it is possible to update the
+  firmware of the radio chip in the run-time, thus bringing it to the
+  most recent version. Unfortunately I couldn't find any mentioning of
+  the said firmware update for the old chips that I tested the driver
+  against, so for chips like that the driver only exposes the old
+  functionality.
+
+
+Parameters exposed over debugfs
+-------------------------------
+SI476x allow user to get multiple characteristics that can be very
+useful for EoL testing/RF performance estimation, parameters that have
+very little to do with V4L2 subsystem. Such parameters are exposed via
+debugfs and can be accessed via regular file I/O operations.
+
+The drivers exposes following files:
+
+* /sys/kernel/debug/<device-name>/acf
+  This file contains ACF(Automatically Controlled Features) status
+  information. The contents of the file is binary data of the
+  following layout:

+ *
+ * Data lines D8-D15 are connected to ISA data lines D0-D7 for reading.

+ * (meaning the bit pattern on A1-A8 can be read back as byte).
+ *
+ * Read and write operations are distinguished by the base address used:
+ * reads are from the ROM A side range, writes are through the B side range
+ * addresses (A side base + 0x10000).
+ *
+ * Reads and writes are byte only.
+ *
+ * 16 bit reads and writes are necessary for the NetUSBee adapter's USB
+ * chipset - 16 bit words are read straight off the ROM port while 16 bit
+ * reads are split into two byte writes. The low byte is latched to the
+ * NetUSBee buffer by a read from the _read_ window (with the data pattern
+ * asserted as A1-A8 address pattern). The high byte is then written to the
+ * write range as usual, completing the write cycle.

+ * to perform this job, hence the use of a deferred delay.
+ *
+ * A deferred delay for thermal monitor is considered safe because:
+ * If the chip gets too hot during a sleep state it's most likely due to
+ * external factors, such as the surrounding temperature. I.e. no SW decisions
+ * will make any difference.

+ * Rafael Micro R820T driver
+ *
+ * Copyright (C) 2013 Mauro Carvalho Chehab <mchehab@redhat.com>
+ *
+ * This driver was written from scratch, based on an existing driver
+ * that it is part of rtl-sdr git tree, released under GPLv2:
+ *	https://groups.google.com/forum/#!topic/ultra-cheap-sdr/Y3rBEOFtHug
+ *	https://github.com/n1gp/gr-baz
+ *
+ * From what I understood from the threads, the original driver was converted
+ * to userspace from a Realtek tree. I couldn't find the original tree.
+ * However, the original driver look awkward on my eyes. So, I decided to
+ * write a new version from it from the scratch, while trying to reproduce
+ * everything found there.
+ *
+ * TODO:
+ *	After locking, the original driver seems to have some routines to
+ *		improve reception. This was not implemented here yet.
+ *
+ *	RF Gain set/get is not implemented.

+ * The stk webcam laptop module is mounted upside down in some laptops :(
+ *
+ * Some background information (thanks to Hans de Goede for providing this):
+ *
+ * 1) Once upon a time the stkwebcam driver was written
+ *
+ * 2) The webcam in question was used mostly in Asus laptop models, including
+ * the laptop of the original author of the driver, and in these models, in
+ * typical Asus fashion (see the long long list for uvc cams inside v4l-utils),
+ * they mounted the webcam-module the wrong way up. So the hflip and vflip
+ * module options were given a default value of 1 (the correct value for
+ * upside down mounted models)
+ *
+ * 3) Years later I got a bug report from a user with a laptop with stkwebcam,
+ * where the module was actually mounted the right way up, and thus showed
+ * upside down under Linux. So now I was facing the choice of 2 options:
+ *
+ * a) Add a not-upside-down list to stkwebcam, which overrules the default.
+ *
+ * b) Do it like all the other drivers do, and make the default right for
+ *    cams mounted the proper way and add an upside-down model list, with
+ *    models where we need to flip-by-default.
+ *
+ * Despite knowing that going b) would cause a period of pain where we were
+ * building the table I opted to go for option b), since a) is just too ugly,
+ * and worse different from how every other driver does it leading to
+ * confusion in the long run. This change was made in kernel 3.6.
+ *
+ * So for any user report about upside-down images since kernel 3.6 ask them
+ * to provide the output of 'sudo dmidecode' so the laptop can be added in
+ * the table below.

+	 * Workaround for errata i743 - LPDDR2 Power-Down State is Not
+	 * Efficient
+	 *
+	 * i743 DESCRIPTION:
+	 * The EMIF supports power-down state for low power. The EMIF
+	 * automatically puts the SDRAM into power-down after the memory is
+	 * not accessed for a defined number of cycles and the
+	 * EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE bit field is set to 0x4.
+	 * As the EMIF supports automatic output impedance calibration, a ZQ
+	 * calibration long command is issued every time it exits active
+	 * power-down and precharge power-down modes. The EMIF waits and
+	 * blocks any other command during this calibration.
+	 * The EMIF does not allow selective disabling of ZQ calibration upon
+	 * exit of power-down mode. Due to very short periods of power-down
+	 * cycles, ZQ calibration overhead creates bandwidth issues and
+	 * increases overall system power consumption. On the other hand,
+	 * issuing ZQ calibration long commands when exiting self-refresh is
+	 * still required.
+	 *
+	 * WORKAROUND
+	 * Because there is no power consumption benefit of the power-down due
+	 * to the calibration and there is a performance risk, the guideline
+	 * is to not allow power-down state and, therefore, to not have set
+	 * the EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE bit field to 0x4.

-	  The Configurable Composite Gadget supports multiple USB
-	  functions: acm, mass storage, rndis and FunctionFS.
-	  Each function can be configured and enabled/disabled
-	  dynamically from userspace through a sysfs interface.
-
-	  In order to compile this (either as a module or built-in),
-	  "USB Gadget Drivers" and anything under it must not be
-	  selected compiled-in in
-	  Device Drivers->USB Support->USB Gadget Support.
-	  However, you can say "M" there, if you do, the
-	  Configurable Composite Gadget can be compiled "M" only
-	  or not at all.
-
-	  BIG FAT NOTE: DON'T RELY ON THIS USERINTERFACE HERE! AS PART
-	  OF THE REWORK DONE HERE WILL BE A NEW USER INTERFACE WITHOUT ANY
-	  COMPATIBILITY TO THIS SYSFS INTERFACE HERE. BE AWARE OF THIS
-	  BEFORE SELECTING THIS.

- * @hs_descriptors: Table of high speed descriptors, using interface and

- * @ss_descriptors: Table of super speed descriptors, using interface and
- *	string identifiers assigned during @bind(). If this
- *	pointer is null after initiation, the function will not
- *	be available at super speed.
- * @config: assigned when @usb_add_function() is called; this is the
- *	configuration with which this function is associated.
- * @bind: Before the gadget can register, all of its functions bind() to the
- *	available resources including string and interface identifiers used
- *	in interface or class descriptors; endpoints; I/O buffers; and so on.
- * @unbind: Reverses @bind; called as a side effect of unregistering the
- *	driver which added this function.
- * @set_alt: (REQUIRED) Reconfigures altsettings; function drivers may
- *	initialize usb_ep.driver data at this time (when it is used).
- *	Note that setting an interface to its current altsetting resets
- *	interface state, and that all interfaces have a disabled state.
- * @get_alt: Returns the active altsetting.  If this is not provided,
- *	then only altsetting zero is supported.
- * @disable: (REQUIRED) Indicates the function should be disabled.  Reasons
- *	include host resetting or reconfiguring the gadget, and disconnection.
- * @setup: Used for interface-specific control requests.
- * @suspend: Notifies functions when the host stops sending USB traffic.
- * @resume: Notifies functions when the host restarts USB traffic.
- * @get_status: Returns function status as a reply to
- *	GetStatus() request when the recepient is Interface.
- * @func_suspend: callback to be called when
- *	SetFeature(FUNCTION_SUSPEND) is reseived
- *
- * A single USB function uses one or more interfaces, and should in most
- * cases support operation at both full and high speeds.  Each function is
- * associated by @usb_add_function() with a one configuration; that function
- * causes @bind() to be called so resources can be allocated as part of
- * setting up a gadget driver.  Those resources include endpoints, which
- * should be allocated using @usb_ep_autoconfig().
- *
- * To support dual speed operation, a function driver provides descriptors
- * for both high and full speed operation.  Except in rare cases that don't
- * involve bulk endpoints, each speed needs different endpoint descriptors.
- *
- * Function drivers choose their own strategies for managing instance data.
- * The simplest strategy just declares it "static', which means the function
- * can only be activated once.  If the function needs to be exposed in more
- * than one configuration at a given speed, it needs to support multiple
- * usb_function structures (one for each configuration).
- *
- * A more complex strategy might encapsulate a @usb_function structure inside
- * a driver-specific instance structure to allows multiple activations.  An
- * example of multiple activations might be a CDC ACM function that supports
- * two or more distinct instances within the same configuration, providing
- * several independent logical data links to a USB host.

- * @iManufacturer: Used as iManufacturer override if @dev->iManufacturer is
- *	not set. If NULL a default "<system> <release> with <udc>" value
- *	will be used.
- * @iSerialNumber: Used as iSerialNumber override if @dev->iSerialNumber is
- *	not set.
- * @dev: Template descriptor for the device, including default device
- *	identifiers.
- * @strings: tables of strings, keyed by identifiers assigned during @bind
- *	and language IDs provided in control requests
- * @max_speed: Highest speed the driver supports.
- * @needs_serial: set to 1 if the gadget needs userspace to provide
- * 	a serial number.  If one is not provided, warning will be printed.
- * @bind: (REQUIRED) Used to allocate resources that are shared across the
- *	whole device, such as string IDs, and add its configurations using
- *	@usb_add_config(). This may fail by returning a negative errno
- *	value; it should return zero on successful initialization.
- * @unbind: Reverses @bind; called as a side effect of unregistering
- *	this driver.
- * @disconnect: optional driver disconnect method
- * @suspend: Notifies when the host stops sending USB traffic,
- *	after function notifications
- * @resume: Notifies configuration when the host restarts USB traffic,
- *	before function notifications
- *
- * Devices default to reporting self powered operation.  Devices which rely
- * on bus powered operation should report this in their @bind method.
- *
- * Before returning from @bind, various fields in the template descriptor
- * may be overridden.  These include the idVendor/idProduct/bcdDevice values
- * normally to bind the appropriate host side driver, and the three strings
- * (iManufacturer, iProduct, iSerialNumber) normally used to provide user
- * meaningful device identifiers.  (The strings will not be defined unless

- * This CDC ACM function support just wraps control functions and
- * notifications around the generic serial-over-usb code.
- *
- * Because CDC ACM is standardized by the USB-IF, many host operating
- * systems have drivers for it.  Accordingly, ACM is the preferred
- * interop solution for serial-port type connections.  The control
- * models are often not necessary, and in any case don't do much in
- * this bare-bones implementation.
- *
- * Note that even MS-Windows has some support for ACM.  However, that
- * support is somewhat broken because when you use ACM in a composite
- * device, having multiple interfaces confuses the poor OS.  It doesn't
- * seem to understand CDC Union descriptors.  The new "association"
- * descriptors (roughly equivalent to CDC Unions) may sometimes help.

- * MSF is configured by specifying a fsg_config structure.  It has the
- * following fields:
- *
- *	nluns		Number of LUNs function have (anywhere from 1
- *				to FSG_MAX_LUNS which is 8).
- *	luns		An array of LUN configuration values.  This
- *				should be filled for each LUN that
- *				function will include (ie. for "nluns"
- *				LUNs).  Each element of the array has
- *				the following fields:
- *	->filename	The path to the backing file for the LUN.
- *				Required if LUN is not marked as
- *				removable.
- *	->ro		Flag specifying access to the LUN shall be
- *				read-only.  This is implied if CD-ROM
- *				emulation is enabled as well as when
- *				it was impossible to open "filename"
- *				in R/W mode.
- *	->removable	Flag specifying that LUN shall be indicated as
- *				being removable.
- *	->cdrom		Flag specifying that LUN shall be reported as
- *				being a CD-ROM.
- *	->nofua		Flag specifying that FUA flag in SCSI WRITE(10,12)
- *				commands for this LUN shall be ignored.
- *
- *	vendor_name
- *	product_name
- *	release		Information used as a reply to INQUIRY
- *				request.  To use default set to NULL,
- *				NULL, 0xffff respectively.  The first
- *				field should be 8 and the second 16
- *				characters or less.
- *
- *	can_stall	Set to permit function to halt bulk endpoints.
- *				Disabled on some USB devices known not
- *				to work correctly.  You should set it
- *				to true.
- *
- * If "removable" is not set for a LUN then a backing file must be
- * specified.  If it is set, then NULL filename means the LUN's medium
- * is not loaded (an empty string as "filename" in the fsg_config
- * structure causes error).  The CD-ROM emulation includes a single
- * data track and no audio tracks; hence there need be only one
- * backing file per LUN.
- *
- * This function is heavily based on "File-backed Storage Gadget" by
- * Alan Stern which in turn is heavily based on "Gadget Zero" by David
- * Brownell.  The driver's SCSI command interface was based on the
- * "Information technology - Small Computer System Interface - 2"
- * document from X3T9.2 Project 375D, Revision 10L, 7-SEP-93,
- * available at <http://www.t10.org/ftp/t10/drafts/s2/s2-r10l.pdf>.
- * The single exception is opcode 0x23 (READ FORMAT CAPACITIES), which
- * was based on the "Universal Serial Bus Mass Storage Class UFI
- * Command Specification" document, Revision 1.0, December 14, 1998,
- * available at
- * <http://www.usb.org/developers/devclass_docs/usbmass-ufi10.pdf>.

-
-/*
- *				Driver Design
- *
- * The MSF is fairly straightforward.  There is a main kernel
- * thread that handles most of the work.  Interrupt routines field
- * callbacks from the controller driver: bulk- and interrupt-request
- * completion notifications, endpoint-0 events, and disconnect events.
- * Completion events are passed to the main thread by wakeup calls.  Many
- * ep0 requests are handled at interrupt time, but SetInterface,
- * SetConfiguration, and device reset requests are forwarded to the
- * thread in the form of "exceptions" using SIGUSR1 signals (since they
- * should interrupt any ongoing file I/O operations).
- *
- * The thread's main routine implements the standard command/data/status
- * parts of a SCSI interaction.  It and its subroutines are full of tests
- * for pending signals/exceptions -- all this polling is necessary since
- * the kernel has no setjmp/longjmp equivalents.  (Maybe this is an
- * indication that the driver really wants to be running in userspace.)
- * An important point is that so long as the thread is alive it keeps an
- * open reference to the backing file.  This will prevent unmounting
- * the backing file's underlying filesystem and could cause problems
- * during system shutdown, for example.  To prevent such problems, the
- * thread catches INT, TERM, and KILL signals and converts them into
- * an EXIT exception.
- *
- * In normal operation the main thread is started during the gadget's
- * fsg_bind() callback and stopped during fsg_unbind().  But it can
- * also exit when it receives a signal, and there's no point leaving
- * the gadget running when the thread is dead.  As of this moment, MSF
- * provides no way to deregister the gadget when thread dies -- maybe
- * a callback functions is needed.
- *
- * To provide maximum throughput, the driver uses a circular pipeline of
- * buffer heads (struct fsg_buffhd).  In principle the pipeline can be
- * arbitrarily long; in practice the benefits don't justify having more
- * than 2 stages (i.e., double buffering).  But it helps to think of the
- * pipeline as being a long one.  Each buffer head contains a bulk-in and
- * a bulk-out request pointer (since the buffer can be used for both
- * output and input -- directions always are given from the host's
- * point of view) as well as a pointer to the buffer and various state
- * variables.
- *
- * Use of the pipeline follows a simple protocol.  There is a variable
- * (fsg->next_buffhd_to_fill) that points to the next buffer head to use.
- * At any time that buffer head may still be in use from an earlier
- * request, so each buffer head has a state variable indicating whether
- * it is EMPTY, FULL, or BUSY.  Typical use involves waiting for the
- * buffer head to be EMPTY, filling the buffer either by file I/O or by
- * USB I/O (during which the buffer head is BUSY), and marking the buffer
- * head FULL when the I/O is complete.  Then the buffer will be emptied
- * (again possibly by USB I/O, during which it is marked BUSY) and
- * finally marked EMPTY again (possibly by a completion routine).
- *
- * A module parameter tells the driver to avoid stalling the bulk
- * endpoints wherever the transport specification allows.  This is
- * necessary for some UDCs like the SuperH, which cannot reliably clear a
- * halt on a bulk endpoint.  However, under certain circumstances the
- * Bulk-only specification requires a stall.  In such cases the driver
- * will halt the endpoint and set a flag indicating that it should clear
- * the halt in software during the next device reset.  Hopefully this
- * will permit everything to work correctly.  Furthermore, although the
- * specification allows the bulk-out endpoint to halt when the host sends
- * too much data, implementing this would cause an unavoidable race.
- * The driver will always use the "no-stall" approach for OUT transfers.
- *
- * One subtle point concerns sending status-stage responses for ep0
- * requests.  Some of these requests, such as device reset, can involve
- * interrupting an ongoing file I/O operation, which might take an
- * arbitrarily long time.  During that delay the host might give up on
- * the original ep0 request and issue a new one.  When that happens the
- * driver should not notify the host about completion of the original
- * request, as the host will no longer be waiting for it.  So the driver
- * assigns to each ep0 request a unique tag, and it keeps track of the
- * tag value of the request associated with a long-running exception
- * (device-reset, interface-change, or configuration-change).  When the
- * exception handler is finished, the status-stage response is submitted
- * only if the current ep0 request tag is equal to the exception request
- * tag.  Thus only the most recently received ep0 request will get a
- * status-stage response.
- *
- * Warning: This driver source file is too long.  It ought to be split up
- * into a header file plus about 3 separate .c files, to handle the details
- * of the Gadget, USB Mass Storage, and SCSI protocols.

-/*
- * This function is an RNDIS Ethernet port -- a Microsoft protocol that's
- * been promoted instead of the standard CDC Ethernet.  The published RNDIS
- * spec is ambiguous, incomplete, and needlessly complex.  Variants such as
- * ActiveSync have even worse status in terms of specification.
- *
- * In short:  it's a protocol controlled by (and for) Microsoft, not for an
- * Open ecosystem or markets.  Linux supports it *only* because Microsoft
- * doesn't support the CDC Ethernet standard.
- *
- * The RNDIS data transfer model is complex, with multiple Ethernet packets
- * per USB message, and out of band data.  The control model is built around
- * what's essentially an "RNDIS RPC" protocol.  It's all wrapped in a CDC ACM
- * (modem, not Ethernet) veneer, with those ACM descriptors being entirely
- * useless (they're ignored).  RNDIS expects to be the only function in its
- * configuration, so it's no real help if you need composite devices; and
- * it expects to be the first configuration too.
- *
- * There is a single technical advantage of RNDIS over CDC Ethernet, if you
- * discount the fluff that its RPC can be made to deliver: it doesn't need
- * a NOP altsetting for the data interface.  That lets it work on some of the
- * "so smart it's stupid" hardware which takes over configuration changes
- * from the software, and adds restrictions like "no altsettings".
- *
- * Unfortunately MSFT's RNDIS drivers are buggy.  They hang or oops, and
- * have all sorts of contrary-to-specification oddities that can prevent
- * them from working sanely.  Since bugfixes (or accurate specs, letting
- * Linux work around those bugs) are unlikely to ever come from MSFT, you
- * may want to avoid using RNDIS on purely operational grounds.
- *
- * Omissions from the RNDIS 1.0 specification include:
- *
- *   - Power management ... references data that's scattered around lots
- *     of other documentation, which is incorrect/incomplete there too.
- *
- *   - There are various undocumented protocol requirements, like the need
- *     to send garbage in some control-OUT messages.
- *
- *   - MS-Windows drivers sometimes emit undocumented requests.

- * This component encapsulates the TTY layer glue needed to provide basic

- * port is exposed through a /dev/ttyGS* node.
- *
- * After initialization (gserial_setup), these TTY port devices stay
- * available until they are removed (gserial_cleanup).  Each one may be
- * connected to a USB function (gserial_connect), or disconnected (with
- * gserial_disconnect) when the USB host issues a config change event.
- * Data can only flow when the port is connected to the host.
- *
- * A given TTY port can be made available in multiple configurations.
- * For example, each one might expose a ttyGS0 node which provides a
- * login application.  In one case that might use CDC ACM interface 0,
- * while another configuration might use interface 3 for that.  The
- * work to handle that (including descriptor management) is not part
- * of this component.
- *
- * Configurations may expose more than one TTY port.  For example, if
- * ttyGS0 provides login service, then ttyGS1 might provide dialer access
- * for a telephone or fax link.  And ttyGS2 might be something that just
- * needs a simple byte stream interface for some messaging protocol that
- * is managed in userspace ... OBEX, PTP, and MTP have been mentioned.

+Driver: adv_1724
+Description: Advantech PCI-1724U
+Author: Frank Mori Hess <fmh6jj@gmail.com>
+Status: works
+Updated: 2013-02-09
+Devices: [Advantech] PCI-1724U (adv_pci1724)
+
+Subdevice 0 is the analog output.
+Subdevice 1 is the offset calibration for the analog output.
+Subdevice 2 is the gain calibration for the analog output.
+
+The calibration offset and gains have quite a large effect
+on the analog output, so it is possible to adjust the analog output to
+have an output range significantly different from the board's
+nominal output ranges.  For a calibrated +/- 10V range, the analog
+output's offset will be set somewhere near mid-range (0x2000) and its
+gain will be near maximum (0x3fff).
+
+There is really no difference between the board's documented 0-20mA
+versus 4-20mA output ranges.  To pick one or the other is simply a matter
+of adjusting the offset and gain calibration until the board outputs in
+the desired range.
+
+Configuration options:
+   None
+
+Manual configuration of comedi devices is not supported by this driver;
+supported PCI devices are configured as comedi devices automatically.

+ * Each PPI is a 8255 chip providing 24 DIO channels.  The DIO channels
+ * are configurable as inputs or outputs in four groups:
+ *
+ *   Port A  - channels  0 to  7
+ *   Port B  - channels  8 to 15
+ *   Port CL - channels 16 to 19
+ *   Port CH - channels 20 to 23
+ *
+ * Only mode 0 of the 8255 chips is supported.
+ *
+ * Each CTR is a 8254 chip providing 3 16-bit counter channels.  Each
+ * channel is configured individually with INSN_CONFIG instructions.  The
+ * specific type of configuration instruction is specified in data[0].
+ * Some configuration instructions expect an additional parameter in
+ * data[1]; others return a value in data[1].  The following configuration
+ * instructions are supported:
+ *
+ *   INSN_CONFIG_SET_COUNTER_MODE.  Sets the counter channel's mode and
+ *     BCD/binary setting specified in data[1].
+ *
+ *   INSN_CONFIG_8254_READ_STATUS.  Reads the status register value for the
+ *     counter channel into data[1].
+ *
+ *   INSN_CONFIG_SET_CLOCK_SRC.  Sets the counter channel's clock source as
+ *     specified in data[1] (this is a hardware-specific value).  Not
+ *     supported on PC214E.  For the other boards, valid clock sources are
+ *     0 to 7 as follows:
+ *
+ *       0.  CLK n, the counter channel's dedicated CLK input from the SK1
+ *         connector.  (N.B. for other values, the counter channel's CLKn
+ *         pin on the SK1 connector is an output!)
+ *       1.  Internal 10 MHz clock.
+ *       2.  Internal 1 MHz clock.
+ *       3.  Internal 100 kHz clock.
+ *       4.  Internal 10 kHz clock.
+ *       5.  Internal 1 kHz clock.
+ *       6.  OUT n-1, the output of counter channel n-1 (see note 1 below).
+ *       7.  Ext Clock, the counter chip's dedicated Ext Clock input from
+ *         the SK1 connector.  This pin is shared by all three counter
+ *         channels on the chip.
+ *
+ *     For the PCIe boards, clock sources in the range 0 to 31 are allowed
+ *     and the following additional clock sources are defined:
+ *
+ *       8.  HIGH logic level.
+ *       9.  LOW logic level.
+ *      10.  "Pattern present" signal.
+ *      11.  Internal 20 MHz clock.
+ *
+ *   INSN_CONFIG_GET_CLOCK_SRC.  Returns the counter channel's current
+ *     clock source in data[1].  For internal clock sources, data[2] is set
+ *     to the period in ns.
+ *
+ *   INSN_CONFIG_SET_GATE_SRC.  Sets the counter channel's gate source as
+ *     specified in data[2] (this is a hardware-specific value).  Not
+ *     supported on PC214E.  For the other boards, valid gate sources are 0
+ *     to 7 as follows:
+ *
+ *       0.  VCC (internal +5V d.c.), i.e. gate permanently enabled.
+ *       1.  GND (internal 0V d.c.), i.e. gate permanently disabled.
+ *       2.  GAT n, the counter channel's dedicated GAT input from the SK1
+ *         connector.  (N.B. for other values, the counter channel's GATn
+ *         pin on the SK1 connector is an output!)
+ *       3.  /OUT n-2, the inverted output of counter channel n-2 (see note
+ *         2 below).
+ *       4.  Reserved.
+ *       5.  Reserved.
+ *       6.  Reserved.
+ *       7.  Reserved.
+ *
+ *     For the PCIe boards, gate sources in the range 0 to 31 are allowed;
+ *     the following additional clock sources and clock sources 6 and 7 are
+ *     (re)defined:
+ *
+ *       6.  /GAT n, negated version of the counter channel's dedicated
+ *         GAT input (negated version of gate source 2).
+ *       7.  OUT n-2, the non-inverted output of counter channel n-2
+ *         (negated version of gate source 3).
+ *       8.  "Pattern present" signal, HIGH while pattern present.
+ *       9.  "Pattern occurred" latched signal, latches HIGH when pattern
+ *         occurs.
+ *      10.  "Pattern gone away" latched signal, latches LOW when pattern
+ *         goes away after it occurred.
+ *      11.  Negated "pattern present" signal, LOW while pattern present
+ *         (negated version of gate source 8).
+ *      12.  Negated "pattern occurred" latched signal, latches LOW when
+ *         pattern occurs (negated version of gate source 9).
+ *      13.  Negated "pattern gone away" latched signal, latches LOW when
+ *         pattern goes away after it occurred (negated version of gate
+ *         source 10).
+ *
+ *   INSN_CONFIG_GET_GATE_SRC.  Returns the counter channel's current gate
+ *     source in data[2].
+ *
+ * Clock and gate interconnection notes:
+ *
+ *   1.  Clock source OUT n-1 is the output of the preceding channel on the
+ *   same counter subdevice if n > 0, or the output of channel 2 on the
+ *   preceding counter subdevice (see note 3) if n = 0.
+ *
+ *   2.  Gate source /OUT n-2 is the inverted output of channel 0 on the
+ *   same counter subdevice if n = 2, or the inverted output of channel n+1
+ *   on the preceding counter subdevice (see note 3) if n < 2.
+ *
+ *   3.  The counter subdevices are connected in a ring, so the highest
+ *   counter subdevice precedes the lowest.
+ *
+ * The 'TIMER' subdevice is a free-running 32-bit timer subdevice.
+ *
+ * The 'INTERRUPT' subdevice pretends to be a digital input subdevice.  The
+ * digital inputs come from the interrupt status register.  The number of
+ * channels matches the number of interrupt sources.  The PC214E does not
+ * have an interrupt status register; see notes on 'INTERRUPT SOURCES'
+ * below.

+ *
+ * When an interrupt source is enabled in the interrupt source enable
+ * register, a rising edge on the source signal latches the corresponding
+ * bit to 1 in the interrupt status register.
+ *
+ * When the interrupt status register value as a whole (actually, just the
+ * 6 least significant bits) goes from zero to non-zero, the board will
+ * generate an interrupt.  The interrupt will remain asserted until the
+ * interrupt status register is cleared to zero.  To clear a bit to zero in
+ * the interrupt status register, the corresponding interrupt source must
+ * be disabled in the interrupt source enable register (there is no
+ * separate interrupt clear register).
+ *
+ * COMMANDS
+ *
+ * The driver supports a read streaming acquisition command on the
+ * 'INTERRUPT' subdevice.  The channel list selects the interrupt sources
+ * to be enabled.  All channels will be sampled together (convert_src ==
+ * TRIG_NOW).  The scan begins a short time after the hardware interrupt
+ * occurs, subject to interrupt latencies (scan_begin_src == TRIG_EXT,
+ * scan_begin_arg == 0).  The value read from the interrupt status register
+ * is packed into a short value, one bit per requested channel, in the
+ * order they appear in the channel list.

-Devices: [National Instruments] Lab-PC-1200 (labpc-1200),
-  Lab-PC-1200AI (labpc-1200ai), Lab-PC+ (lab-pc+), PCI-1200 (ni_labpc)
-Status: works
-
-Tested with lab-pc-1200.  For the older Lab-PC+, not all input ranges
-and analog references will work, the available ranges/arefs will
-depend on how you have configured the jumpers on your board
-(see your owner's manual).
-
-Kernel-level ISA plug-and-play support for the lab-pc-1200
-boards has not
-yet been added to the driver, mainly due to the fact that
-I don't know the device id numbers.  If you have one
-of these boards,
-please file a bug report at http://comedi.org/ 
-so I can get the necessary information from you.
-
-The 1200 series boards have onboard calibration dacs for correcting
-analog input/output offsets and gains.  The proper settings for these
-caldacs are stored on the board's eeprom.  To read the caldac values
-from the eeprom and store them into a file that can be then be used by
-comedilib, use the comedi_calibrate program.
-
-Configuration options - ISA boards:
-  [0] - I/O port base address
-  [1] - IRQ (optional, required for timed or externally triggered conversions)
-  [2] - DMA channel (optional)
-
-Configuration options - PCI boards:
-  [0] - bus (optional)
-  [1] - slot (optional)
-
-The Lab-pc+ has quirky chanlist requirements
-when scanning multiple channels.  Multiple channel scan
-sequence must start at highest channel, then decrement down to
-channel 0.  The rest of the cards can scan down like lab-pc+ or scan
-up from channel zero.  Chanlists consisting of all one channel
-are also legal, and allow you to pace conversions in bursts.

-    The PCI4520 is a PCI card.  The DM7520 is a PC/104-plus card.
-    Both have:
-    8/16 12 bit ADC with FIFO and channel gain table
-    8 bits high speed digital out (for external MUX) (or 8 in or 8 out)
-    8 bits high speed digital in with FIFO and interrupt on change (or 8 IO)
-    2 12 bit DACs with FIFOs
-    2 bits output
-    2 bits input
-    bus mastering DMA
-    timers: ADC sample, pacer, burst, about, delay, DA1, DA2
-    sample counter
-    3 user timer/counters (8254)
-    external interrupt
-
-    The DM7520 has slightly fewer features (fewer gain steps).
-
-    These boards can support external multiplexors and multi-board
-    synchronization, but this driver doesn't support that.

-    Board docs: http://www.rtdusa.com/PC104/DM/analog%20IO/dm7520.htm
-    Data sheet: http://www.rtdusa.com/pdf/dm7520.pdf

-    PCI chip: http://www.plxtech.com/products/io/pci9080
-
-    Notes:
-    This board is memory mapped.  There is some IO stuff, but it isn't needed.
-
-    I use a pretty loose naming style within the driver (rtd_blah).
-    All externally visible names should be rtd520_blah.
-    I use camelCase for structures (and inside them).
-    I may also use upper CamelCase for function names (old habit).
-
-    This board is somewhat related to the RTD PCI4400 board.
-
-    I borrowed heavily from the ni_mio_common, ni_atmio16d, mite, and
-    das1800, since they have the best documented code.  Driver
-    cb_pcidas64.c uses the same DMA controller.
-
-    As far as I can tell, the About interrupt doesn't work if Sample is
-    also enabled.  It turns out that About really isn't needed, since
-    we always count down samples read.
-
-    There was some timer/counter code, but it didn't follow the right API.

-  With DMA, you can sample at 1.15Mhz with 70% idle on a 400Mhz K6-2

+ * @max_transfer_size:  The maximum transfer size supported, in bytes
+ *                       2047 to 65,535 (default 65,535)

+ *                      the driver will automatically detect the phy_type.
+ * @phy_utmi_width:     Specifies the UTMI+ Data Width (in bits). This parameter
+ *                      is applicable for a phy_type of UTMI+ or ULPI. (For a
+ *                      ULPI phy_type, this parameter indicates the data width
+ *                      between the MAC and the ULPI Wrapper.) Also, this
+ *                      parameter is applicable only if the OTG_HSPHY_WIDTH cC
+ *                      parameter was set to "8 and 16 bits", meaning that the
+ *                      core has been configured to work at either data path
+ *                      width.

+ *                      a transfer for DMA mode of operation.
+ *                       0 - remainder data will be sent using INCR burst size
+ *                       1 - remainder data will be sent using SINGLE burst size

+ * @op_state:           The operational State, during transitions (a_host=>
+ *                      a_peripheral and b_device=>b_host) this may not match
+ *                      the core, but allows the software to determine

+ * @wkp_timer:          Timer object for handling Wakeup Detected interrupt
+ * @lx_state:           Lx state of connected device
+ * @flags:              Flags for handling root port state changes
+ * @non_periodic_sched_inactive: Inactive QHs in the non-periodic schedule.
+ *                      Transfers associated with these QHs are not currently
+ *                      assigned to a host channel.

+ *                      assigned to a host channel.
+ * @non_periodic_qh_ptr: Pointer to next QH to process in the active
+ *                      non-periodic schedule
+ * @periodic_sched_inactive: Inactive QHs in the periodic schedule. This is a
+ *                      list of QHs for periodic transfers that are _not_
+ *                      scheduled for the next frame. Each QH in the list has an
+ *                      interval counter that determines when it needs to be
+ *                      scheduled for execution. This scheduling mechanism
+ *                      allows only a simple calculation for periodic bandwidth
+ *                      used (i.e. must assume that all periodic transfers may
+ *                      need to execute in the same frame). However, it greatly
+ *                      simplifies scheduling and should be sufficient for the
+ *                      vast majority of OTG hosts, which need to connect to a
+ *                      small number of peripherals at one time. Items move from
+ *                      this list to periodic_sched_ready when the QH interval
+ *                      counter is 0 at SOF.
+ * @periodic_sched_ready:  List of periodic QHs that are ready for execution in
+ *                      the next frame, but have not yet been assigned to host
+ *                      channels. Items move from this list to
+ *                      periodic_sched_assigned as host channels become
+ *                      available during the current frame.
+ * @periodic_sched_assigned: List of periodic QHs to be executed in the next
+ *                      frame that are assigned to host channels. Items move
+ *                      from this list to periodic_sched_queued as the
+ *                      transactions for the QH are queued to the DWC_otg
+ *                      controller.
+ * @periodic_sched_queued: List of periodic QHs that have been queued for
+ *                      execution. Items move from this list to either
+ *                      periodic_sched_inactive or periodic_sched_ready when the
+ *                      channel associated with the transfer is released. If the
+ *                      interval for the QH is 1, the item moves to
+ *                      periodic_sched_ready because it must be rescheduled for
+ *                      the next frame. Otherwise, the item moves to
+ *                      periodic_sched_inactive.
+ * @periodic_usecs:     Total bandwidth claimed so far for periodic transfers.
+ *                      This value is in microseconds per (micro)frame. The
+ *                      assumption is that all periodic transfers may occur in
+ *                      the same (micro)frame.
+ * @frame_number:       Frame number read from the core at SOF. The value ranges
+ *                      from 0 to HFNUM_MAX_FRNUM.
+ * @periodic_qh_count:  Count of periodic QHs, if using several eps. Used for
+ *                      SOF enable/disable.
+ * @free_hc_list:       Free host channels in the controller. This is a list of
+ *                      struct dwc2_host_chan items.
+ * @periodic_channels:  Number of host channels assigned to periodic transfers.
+ *                      Currently assuming that there is a dedicated host
+ *                      channel for each periodic transaction and at least one
+ *                      host channel is available for non-periodic transactions.
+ * @non_periodic_channels: Number of host channels assigned to non-periodic
+ *                      transfers
+ * @hc_ptr_array:       Array of pointers to the host channel descriptors.
+ *                      Allows accessing a host channel descriptor given the
+ *                      host channel number. This is useful in interrupt
+ *                      handlers.
+ * @status_buf:         Buffer used for data received during the status phase of
+ *                      a control transfer.
+ * @status_buf_dma:     DMA address for status_buf
+ * @start_work:         Delayed work for handling host A-cable connection
+ * @reset_work:         Delayed work for handling a port reset
+ * @lock:               Spinlock that protects all the driver data structures
+ * @priv:               Stores a pointer to the struct usb_hcd
+ * @otg_port:           OTG port number
+ * @frame_list:         Frame list
+ * @frame_list_dma:     Frame list DMA address

 Todo:
-	- checkpatch.pl cleanups
-	- sparse cleanups
-	- lots of little modules, should be merged together
-	  and added to the build.
-	- testing?
-	- handle churn in v4l layer.
+	- create an API for motion detection
+	- let s2250-board use i2c subdevs as well instead of hardcoding
+	  support for the i2c devices.
+	- when the driver is moved out of staging, support for saa7134-go7007
+	  should be added to the saa7134 driver. The patch for that is
+	  included below.
 
-Please send patches to Greg Kroah-Hartman <greg@linuxfoundation.org> and Cc: Ross

-List of TODOs (by Eduardo Valentin)
-
-on omap-bandgap.c:
-- Rework locking
-- Improve driver code by adding usage of regmap-mmio
-- Test every exposed API to userland
-- Add support to hwmon
-- Review and revisit all API exposed
-- Revisit PM support
-- Revisit data structures and simplify them
-- Once SCM-core api settles, update this driver accordingly
-
-on omap-thermal-common.c/omap-thermal.h:
-- Revisit extrapolation constants for O4/O5
-- Revisit need for locking
-- Revisit trips and its definitions
-- Revisit trending
-
-on omap5-thermal.c
-- Add support for GPU cooling
-
-generally:
-- write Kconfig dependencies so that omap variants are covered
-- make checkpatch.pl and sparse happy
-- make sure this code works on OMAP4430, OMAP4460 and OMAP5430
-- update documentation

-* Texas Instrument OMAP SCM bandgap bindings
-
-In the System Control Module, OMAP supplies a voltage reference
-and a temperature sensor feature that are gathered in the band
-gap voltage and temperature sensor (VBGAPTS) module. The band
-gap provides current and voltage reference for its internal
-circuits and other analog IP blocks. The analog-to-digital
-converter (ADC) produces an output value that is proportional
-to the silicon temperature.
-
-Required properties:
-- compatible : Should be:
-  - "ti,omap4460-control-bandgap" : for OMAP4460 bandgap
-  - "ti,omap5430-control-bandgap" : for OMAP5430 bandgap
-- interrupts : this entry should indicate which interrupt line
-the talert signal is routed to;
-Specific:
-- ti,tshut-gpio : this entry should be used to inform which GPIO
-line the tshut signal is routed to;
-
-Example:
-
-bandgap {
-	reg = <0x4a002260 0x4
-		0x4a00232C 0x4
-		0x4a002378 0x18>;
-	compatible = "ti,omap4460-control-bandgap";
-	interrupts = <0 126 4>; /* talert */
-	ti,tshut-gpio = <86>;

+ * DOC: ti bandgap feature types
+ *
+ * TI_BANDGAP_FEATURE_TSHUT - used when the thermal shutdown signal output
+ *      of a bandgap device instance is routed to the processor. This means
+ *      the system must react and perform the shutdown by itself (handle an
+ *      IRQ, for instance).
+ *
+ * TI_BANDGAP_FEATURE_TSHUT_CONFIG - used when the bandgap device has control
+ *      over the thermal shutdown configuration. This means that the thermal
+ *      shutdown thresholds are programmable, for instance.
+ *
+ * TI_BANDGAP_FEATURE_TALERT - used when the bandgap device instance outputs
+ *      a signal representing violation of programmable alert thresholds.
+ *
+ * TI_BANDGAP_FEATURE_MODE_CONFIG - used when it is possible to choose which
+ *      mode, continuous or one shot, the bandgap device instance will operate.
+ *
+ * TI_BANDGAP_FEATURE_COUNTER - used when the bandgap device instance allows
+ *      programming the update interval of its internal state machine.
+ *
+ * TI_BANDGAP_FEATURE_POWER_SWITCH - used when the bandgap device allows
+ *      itself to be switched on/off.
+ *
+ * TI_BANDGAP_FEATURE_CLK_CTRL - used when the clocks feeding the bandgap
+ *      device are gateable or not.
+ *
+ * TI_BANDGAP_FEATURE_FREEZE_BIT - used when the bandgap device features
+ *      a history buffer that its update can be freezed/unfreezed.
+ *
+ * TI_BANDGAP_FEATURE_COUNTER_DELAY - used when the bandgap device features
+ *	a delay programming based on distinct values.
+ *
+ * TI_BANDGAP_FEATURE_HISTORY_BUFFER - used when the bandgap device features
+ *	a history buffer of temperatures.
+ *
+ * TI_BANDGAP_HAS(b, f) - macro to check if a bandgap device is capable of a
+ *      specific feature (above) or not. Return non-zero, if yes.

+* Texas Instrument OMAP SCM bandgap bindings
+
+In the System Control Module, OMAP supplies a voltage reference
+and a temperature sensor feature that are gathered in the band
+gap voltage and temperature sensor (VBGAPTS) module. The band
+gap provides current and voltage reference for its internal
+circuits and other analog IP blocks. The analog-to-digital
+converter (ADC) produces an output value that is proportional
+to the silicon temperature.
+
+Required properties:
+- compatible : Should be:
+  - "ti,omap4430-bandgap" : for OMAP4430 bandgap
+  - "ti,omap4460-bandgap" : for OMAP4460 bandgap
+  - "ti,omap4470-bandgap" : for OMAP4470 bandgap
+  - "ti,omap5430-bandgap" : for OMAP5430 bandgap
+- interrupts : this entry should indicate which interrupt line
+the talert signal is routed to;
+Specific:
+- ti,tshut-gpio : this entry should be used to inform which GPIO
+line the tshut signal is routed to;
+- regs : this entry must also be specified and it is specific
+to each bandgap version, because the mapping may change from
+soc to soc, apart of depending on available features.
+
+Example:
+OMAP4430:
+bandgap {
+	reg = <0x4a002260 0x4 0x4a00232C 0x4>;
+	compatible = "ti,omap4430-bandgap";
+};
+
+OMAP4460:
+bandgap {
+	reg = <0x4a002260 0x4
+		0x4a00232C 0x4
+		0x4a002378 0x18>;
+	compatible = "ti,omap4460-bandgap";
+	interrupts = <0 126 4>; /* talert */
+	ti,tshut-gpio = <86>;
+};
+
+OMAP4470:
+bandgap {
+	reg = <0x4a002260 0x4
+		0x4a00232C 0x4
+		0x4a002378 0x18>;
+	compatible = "ti,omap4470-bandgap";
+	interrupts = <0 126 4>; /* talert */
+	ti,tshut-gpio = <86>;
+};
+
+OMAP5430:
+bandgap {
+	reg = <0x4a0021e0 0xc
+		0x4a00232c 0xc
+		0x4a002380 0x2c
+		0x4a0023C0 0x3c>;
+	compatible = "ti,omap5430-bandgap";
+};

  * Video queues is initialized by uvc_queue_init(). The function performs
  * basic initialization of the uvc_video_queue struct and never fails.
  *
- * Video buffer allocation and freeing are performed by uvc_alloc_buffers and
- * uvc_free_buffers respectively. The former acquires the video queue lock,
- * while the later must be called with the lock held (so that allocation can
- * free previously allocated buffers). Trying to free buffers that are mapped
- * to user space will return -EBUSY.
- *
- * Video buffers are managed using two queues. However, unlike most USB video
- * drivers that use an in queue and an out queue, we use a main queue to hold
- * all queued buffers (both 'empty' and 'done' buffers), and an irq queue to
- * hold empty buffers. This design (copied from video-buf) minimizes locking
- * in interrupt, as only one queue is shared between interrupt and user
- * contexts.
- *
- * Use cases
- * ---------
- *
- * Unless stated otherwise, all operations that modify the irq buffers queue
- * are protected by the irq spinlock.
- *
- * 1. The user queues the buffers, starts streaming and dequeues a buffer.
- *
- *    The buffers are added to the main and irq queues. Both operations are
- *    protected by the queue lock, and the later is protected by the irq
- *    spinlock as well.
- *
- *    The completion handler fetches a buffer from the irq queue and fills it
- *    with video data. If no buffer is available (irq queue empty), the handler
- *    returns immediately.
- *
- *    When the buffer is full, the completion handler removes it from the irq
- *    queue, marks it as ready (UVC_BUF_STATE_DONE) and wakes its wait queue.
- *    At that point, any process waiting on the buffer will be woken up. If a
- *    process tries to dequeue a buffer after it has been marked ready, the
- *    dequeing will succeed immediately.
- *
- * 2. Buffers are queued, user is waiting on a buffer and the device gets
- *    disconnected.
- *
- *    When the device is disconnected, the kernel calls the completion handler
- *    with an appropriate status code. The handler marks all buffers in the
- *    irq queue as being erroneous (UVC_BUF_STATE_ERROR) and wakes them up so
- *    that any process waiting on a buffer gets woken up.
- *
- *    Waking up up the first buffer on the irq list is not enough, as the
- *    process waiting on the buffer might restart the dequeue operation
- *    immediately.
- *
+ * Video buffers are managed by videobuf2. The driver uses a mutex to protect
+ * the videobuf2 queue operations by serializing calls to videobuf2 and a
+ * spinlock to protect the IRQ queue that holds the buffers to be processed by
+ * the driver.

-/* MUSB PERIPHERAL status 3-mar-2006:
- *
- * - EP0 seems solid.  It passes both USBCV and usbtest control cases.
- *   Minor glitches:
- *
- *     + remote wakeup to Linux hosts work, but saw USBCV failures;
- *       in one test run (operator error?)
- *     + endpoint halt tests -- in both usbtest and usbcv -- seem
- *       to break when dma is enabled ... is something wrongly
- *       clearing SENDSTALL?
- *
- * - Mass storage behaved ok when last tested.  Network traffic patterns
- *   (with lots of short transfers etc) need retesting; they turn up the
- *   worst cases of the DMA, since short packets are typical but are not
- *   required.
- *
- * - TX/IN
- *     + both pio and dma behave in with network and g_zero tests
- *     + no cppi throughput issues other than no-hw-queueing
- *     + failed with FLAT_REG (DaVinci)
- *     + seems to behave with double buffering, PIO -and- CPPI
- *     + with gadgetfs + AIO, requests got lost?
- *
- * - RX/OUT
- *     + both pio and dma behave in with network and g_zero tests
- *     + dma is slow in typical case (short_not_ok is clear)
- *     + double buffering ok with PIO
- *     + double buffering *FAILS* with CPPI, wrong data bytes sometimes
- *     + request lossage observed with gadgetfs
- *
- * - ISO not tested ... might work, but only weakly isochronous
- *
- * - Gadget driver disabling of softconnect during bind() is ignored; so
- *   drivers can't hold off host requests until userspace is ready.
- *   (Workaround:  they can turn it off later.)
- *
- * - PORTABILITY (assumes PIO works):
- *     + DaVinci, basically works with cppi dma
- *     + OMAP 2430, ditto with mentor dma
- *     + TUSB 6010, platform-specific dma in the works

+ * simplify our code by using a 32-bit big-endian integer ("line") to read in
+ * a single line of pixels, and only look at the top 'width' bits of that
+ * integer.
+ *
+ * This could result in an unaligned 32-bit read.  For example, if the cursor
+ * is 24x24, then the first three bytes of 'image' contain the pixel data for
+ * the top line of the cursor.  We do a 32-bit read of 'image', but we look
+ * only at the top 24 bits.  Then we increment 'image' by 3 bytes.  The next

+perf-mem - Profile memory accesses
+
+SYNOPSIS
+--------
+[verse]
+'perf mem' [<options>] (record [<command>] | report)
+
+DESCRIPTION
+-----------
+"perf mem -t <TYPE> record" runs a command and gathers memory operation data
+from it, into perf.data. Perf record options are accepted and are passed through.
+
+"perf mem -t <TYPE> report" displays the result. It invokes perf report with the
+right set of options to display a memory access profile.
+
+OPTIONS
+-------
+<command>...::
+	Any command you can specify in a shell.
+
+-t::
+--type=::
+	Select the memory operation type: load or store (default: load)
+
+-D::
+--dump-raw-samples=::
+	Dump the raw decoded samples on the screen in a format that is easy to parse with
+	one sample per line.
+
+-x::
+--field-separator::
+	Specify the field separator used when dump raw samples (-D option). By default,
+	The separator is the space character.
+
+-C::
+--cpu-list::
+	Restrict dump of raw samples to those provided via this option. Note that the same
+	option can be passed in record mode. It will be interpreted the same way as perf
+	record.
