-Lantiq XWAY SoC RCU USB 1.1/2.0 PHY binding
-===========================================
-
-This binding describes the USB PHY hardware provided by the RCU module on the
-Lantiq XWAY SoCs.
-
-This node has to be a sub node of the Lantiq RCU block.
-
--------------------------------------------------------------------------------
-Required properties (controller (parent) node):
-- compatible	: Should be one of
-			"lantiq,ase-usb2-phy"
-			"lantiq,danube-usb2-phy"
-			"lantiq,xrx100-usb2-phy"
-			"lantiq,xrx200-usb2-phy"
-			"lantiq,xrx300-usb2-phy"
-- reg		: Defines the following sets of registers in the parent
-		  syscon device
-			- Offset of the USB PHY configuration register
-			- Offset of the USB Analog configuration
-			  register (only for xrx200 and xrx200)
-- clocks	: References to the (PMU) "phy" clk gate.
-- clock-names	: Must be "phy"
-- resets	: References to the RCU USB configuration reset bits.
-- reset-names	: Must be one of the following:
-			"phy" (optional)
-			"ctrl" (shared)
-
--------------------------------------------------------------------------------
-Example for the USB PHYs on an xRX200 SoC:
-	usb_phy0: usb2-phy@18 {
-		compatible = "lantiq,xrx200-usb2-phy";
-		reg = <0x18 4>, <0x38 4>;
-
-		clocks = <&pmu PMU_GATE_USB0_PHY>;
-		clock-names = "phy";
-		resets = <&reset1 4 4>, <&reset0 4 4>;
-		reset-names = "phy", "ctrl";
-		#phy-cells = <0>;
-	};
