+ST STiH407 USB PHY controller
+
+This file documents the dt bindings for the usb picoPHY driver which is the PHY for both USB2 and USB3
+host controllers (when controlling usb2/1.1 devices) available on STiH407 SoC family from STMicroelectronics.
+
+Required properties:
+- compatible : should be "st,stih407-usb2-phy"
+- reg : contain the offset and length of the system configuration registers
+ used as glue logic to control & parameter phy
+- reg-names : the names of the system configuration registers in "reg", should be "param" and "reg"
+- st,syscfg : sysconfig register to manage phy parameter at driver level
+- resets : list of phandle and reset specifier pairs. There should be two entries, one
+ for the whole phy and one for the port
+- reset-names : list of reset signal names. Should be "global" and "port"
+See: Documentation/devicetree/bindings/reset/st,sti-powerdown.txt
+See: Documentation/devicetree/bindings/reset/reset.txt
+
+Example:
+
+usb2_picophy0: usbpicophy@f8 {
+ compatible = "st,stih407-usb2-phy";
+ reg = <0xf8 0x04>, /* syscfg 5062 */
+ <0xf4 0x04>; /* syscfg 5061 */

+STMicroelectronics STiH41x USB PHY binding
+------------------------------------------
+
+This file contains documentation for the usb phy found in STiH415/6 SoCs from
+STMicroelectronics.
+
+Required properties:
+- compatible : should be "st,stih416-usb-phy" or "st,stih415-usb-phy"
+- st,syscfg : should be a phandle of the syscfg node
+- clock-names : must contain "osc_phy"
+- clocks : must contain an entry for each name in clock-names.
+See: Documentation/devicetree/bindings/clock/clock-bindings.txt
+- #phy-cells : must be 0 for this phy
+See: Documentation/devicetree/bindings/phy/phy-bindings.txt
+
+Example:
+
+usb2_phy: usb2phy@0 {
+ compatible = "st,stih416-usb-phy";
+ #phy-cell = <0>;

+* Renesas R-Car generation 2 USB PHY
+
+This file provides information on what the device node for the R-Car generation
+2 USB PHY contains.
+
+Required properties:
+- compatible: "renesas,usb-phy-r8a7790" if the device is a part of R8A7790 SoC.
+ "renesas,usb-phy-r8a7791" if the device is a part of R8A7791 SoC.
+- reg: offset and length of the register block.
+- #address-cells: number of address cells for the USB channel subnodes, must
+ be <1>.
+- #size-cells: number of size cells for the USB channel subnodes, must be <0>.
+- clocks: clock phandle and specifier pair.
+- clock-names: string, clock input name, must be "usbhs".
+
+The USB PHY device tree node should have the subnodes corresponding to the USB
+channels. These subnodes must contain the following properties:
+- reg: the USB controller selector; see the table below for the values.
+- #phy-cells: see phy-bindings.txt in the same directory, must be <1>.
+
+The phandle's argument in the PHY specifier is the USB controller selector for
+the USB channel; see the selector meanings below:
+
++-----------+---------------+---------------+
+|\ Selector | | |
++ --------- + 0 | 1 |
+| Channel \| | |
++-----------+---------------+---------------+
+| 0 | PCI EHCI/OHCI | HS-USB |
+| 2 | PCI EHCI/OHCI | xHCI |
++-----------+---------------+---------------+
+
+Example (Lager board):
+
+ usb-phy@e6590100 {
+ compatible = "renesas,usb-phy-r8a7790";
+ reg = <0 0xe6590100 0 0x100>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ clocks = <&mstp7_clks R8A7790_CLK_HSUSB>;
+ clock-names = "usbhs";
+
+ usb-channel@0 {
+ reg = <0>;
+ #phy-cells = <1>;
+ };
+ usb-channel@2 {
+ reg = <2>;
+ #phy-cells = <1>;
+ };
+ };
