-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>;
-	};
-};
