* Amlogic Meson GXL and GXM USB2 PHY binding

Required properties:

- compatible:	Should be "amlogic,meson-gxl-usb2-phy"

- reg:		The base address and length of the registers

- #phys-cells:	must be 0 (see phy-bindings.txt in this directory)

Optional properties:

- clocks:	a phandle to the clock of this PHY

- clock-names:	must be "phy"

- resets:	a phandle to the reset line of this PHY

- reset-names:	must be "phy"

- phy-supply:	see phy-bindings.txt in this directory

Example:

	usb2_phy0: phy@78000 {

		compatible = "amlogic,meson-gxl-usb2-phy";

		#phy-cells = <0>;

		reg = <0x0 0x78000 0x0 0x20>;
