| tristate "Generic Thermal sysfs driver" |
| help |
| Generic Thermal Sysfs driver offers a generic mechanism for |
| thermal management. Usually it's made up of one or more thermal |
| zone and cooling device. |
| Each thermal zone contains its own temperature, trip points, |
| cooling devices. |
| All platforms with ACPI thermal support can use this driver. |
| If you want this support, you should say Y or M here. |

| config THERMAL_HWMON |
| bool |
| prompt "Expose thermal sensors as hwmon device" |
| depends on HWMON=y || HWMON=THERMAL |
| default y |
| help |
| In case a sensor is registered with the thermal |
| framework, this option will also register it |
| as a hwmon. The sensor will then have the common |
| hwmon sysfs interface. |
| |
| Say 'Y' here if you want all thermal sensors to |
| have hwmon sysfs interface too. |

| depends on OF |
| default y |
| help |
| This options provides helpers to add the support to |
| read and parse thermal data definitions out of the |
| device tree blob. |
| |
| Say 'Y' here if you need to build thermal infrastructure |
| based on device tree. |

| help |
| Use the step_wise governor as default. This throttles the |

| select THERMAL_GOV_FAIR_SHARE |
| help |
| Use the fair_share governor as default. This throttles the |
| devices based on their 'contribution' to a zone. The |
| contribution should be provided through platform data. |

| config CPU_THERMAL |
| bool "generic cpu cooling support" |
| depends on CPU_FREQ |
| depends on THERMAL_OF |
| help |
| This implements the generic cpu cooling mechanism through frequency |
| reduction. An ACPI version of this already exists |
| (drivers/acpi/processor_thermal.c). |
| This will be useful for platforms using the generic thermal interface |
| and not the ACPI interface. |
| |
| If you want this support, you should say Y here. |
| |
| config THERMAL_EMULATION |
| bool "Thermal emulation mode support" |
| help |
| Enable this option to make a emul_temp sysfs node in thermal zone |
| directory to support temperature emulation. With emulation sysfs node, |
| user can manually input temperature and test the different trip |
| threshold behaviour for simulation purpose. |
| |
| WARNING: Be careful while enabling this option on production systems, |
| because userland can easily disable the thermal policy by simply |
| flooding this sysfs node with low temperature values. |

| help |
| Support for Temperature Monitor (TEMPMON) found on Freescale i.MX SoCs. |
| It supports one critical trip point and one passive trip point. The |
| cpufreq is used as the cooling device to throttle CPUs when the |
| passive trip is crossed. |

| help |
| Adds DB8500 thermal management implementation according to the thermal |
| management framework. A thermal zone with several trip points will be |
| created. Cooling devices can be bound to the trip points to cool this |
| thermal zone if trip points reached. |

| Adds DB8500 cpufreq cooling devices, and these cooling devices can be |
| bound to thermal zone trip points. When a trip point reached, the |
| bound cpufreq cooling device turns active to set CPU frequency low to |
| cool down the CPU. |
