-- 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>;
