+* Amlogic Meson GXL and GXM USB3 PHY and OTG detection binding
+
+Required properties:
+- compatible:	Should be "amlogic,meson-gxl-usb3-phy"
+- #phys-cells:	must be 0 (see phy-bindings.txt in this directory)
+- reg:		The base address and length of the registers
+- interrupts:	the interrupt specifier for the OTG detection
+- clocks:	phandles to the clocks for
+		- the USB3 PHY
+		- and peripheral mode/OTG detection
+- clock-names:	must contain "phy" and "peripheral"
+- resets:	phandle to the reset lines for:
+		- the USB3 PHY and
+		- peripheral mode/OTG detection
+- reset-names:	must contain "phy" and "peripheral"
+
+Optional properties:
+- phy-supply:	see phy-bindings.txt in this directory
+
+
+Example:
+	usb3_phy0: phy@78080 {
+		compatible = "amlogic,meson-gxl-usb3-phy";
+		#phy-cells = <0>;
+		reg = <0x0 0x78080 0x0 0x20>;
+		interrupts = <GIC_SPI 16 IRQ_TYPE_LEVEL_HIGH>;
+		clocks = <&clkc CLKID_USB_OTG>, <&clkc_AO CLKID_AO_CEC_32K>;
+		clock-names = "phy", "peripheral";
+		resets = <&reset RESET_USB_OTG>, <&reset RESET_USB_OTG>;
+		reset-names = "phy", "peripheral";
+	};
