+Device Tree bindings for Freescale DCU DRM Driver
+
+Required properties:
+- compatible:		Should be one of
+	* "fsl,ls1021a-dcu".
+	* "fsl,vf610-dcu".
+
+- reg:			Address and length of the register set for dcu.
+- clocks:		Handle to "dcu" and "pix" clock (in the order below)
+			This can be the same clock (e.g. LS1021a)
+			See ../clocks/clock-bindings.txt for details.
+- clock-names:		Should be "dcu" and "pix"
+			See ../clocks/clock-bindings.txt for details.
+- big-endian		Boolean property, LS1021A DCU registers are big-endian.
+- port			Video port for the panel output
+
+Optional properties:
+- fsl,tcon:		The phandle to the timing controller node.
+
+Examples:
+dcu: dcu@2ce0000 {
+	compatible = "fsl,ls1021a-dcu";
+	reg = <0x0 0x2ce0000 0x0 0x10000>;
+	clocks = <&platform_clk 0>, <&platform_clk 0>;
+	clock-names = "dcu", "pix";
+	big-endian;
+	fsl,tcon = <&tcon>;
+
+	port {
+		dcu_out: endpoint {
+			remote-endpoint = <&panel_out>;
+	     };
+	};
+};
