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>;

	     };

	};

};
