+* 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@...00 {
+		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>;
+	};
