-* Freescale i.MX8MQ USB3 PHY binding
-
-Required properties:
-- compatible:	Should be "fsl,imx8mq-usb-phy" or "fsl,imx8mp-usb-phy"
-- #phys-cells:	must be 0 (see phy-bindings.txt in this directory)
-- reg:		The base address and length of the registers
-- clocks:	phandles to the clocks for each clock listed in clock-names
-- clock-names:	must contain "phy"
-
-Optional properties:
-- vbus-supply: A phandle to the regulator for USB VBUS.
-
-Example:
-	usb3_phy0: phy@381f0040 {
-		compatible = "fsl,imx8mq-usb-phy";
-		reg = <0x381f0040 0x40>;
-		clocks = <&clk IMX8MQ_CLK_USB1_PHY_ROOT>;
-		clock-names = "phy";
-		#phy-cells = <0>;
-	};
