+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 */

+------------------------------------------
+
+This file contains documentation for the usb phy found in STiH415/6 SoCs from

+
+Required properties:
+- compatible	: should be "st,stih416-usb-phy" or "st,stih415-usb-phy"

+- 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

+* 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>;
