* Amlogic G12A USB2 PHY binding

Required properties:

- compatible:	Should be "amlogic,meson-g12a-usb2-phy"

- reg:		The base address and length of the registers

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

- clocks:	a phandle to the clock of this PHY

- clock-names:	must be "xtal"

- 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@36000 {

		compatible = "amlogic,g12a-usb2-phy";

		reg = <0x0 0x36000 0x0 0x2000>;

		clocks = <&xtal>;

		clock-names = "xtal";

		resets = <&reset RESET_USB_PHY21>;

		reset-names = "phy";

		#phy-cells = <0>;
