NXP LPC18xx/43xx internal USB OTG PHY binding
---------------------------------------------

This file contains documentation for the internal USB OTG PHY found
in NXP LPC18xx and LPC43xx SoCs.

Required properties:
- compatible	: must be "nxp,lpc1850-usb-otg-phy"
- clocks	: must be exactly one entry
See: Documentation/devicetree/bindings/clock/clock-bindings.txt
- #phy-cells	: must be 0 for this phy
See: Documentation/devicetree/bindings/phy/phy-bindings.txt

The phy node must be a child of the creg syscon node.

Example:
creg: syscon@40043000 {
	compatible = "nxp,lpc1850-creg", "syscon", "simple-mfd";
	reg = <0x40043000 0x1000>;

	usb0_otg_phy: phy {
		compatible = "nxp,lpc1850-usb-otg-phy";
		clocks = <&ccu1 CLK_USB0>;
		#phy-cells = <0>;
	};
};
