+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:               From common clock binding: handle to dcu clock.
+- clock-names:          From common clock binding: Shall be "dcu".
+- display:              The phandle to display node.
+
+Required properties:
+- bits-per-pixel:       <16> for RGB565,
+			<24> for RGB888,
+			<32> for RGB8888.
+
+Required timing node for dispplay sub-node:
+- display-timings:      Refer to binding doc display-timing.txt for details.
+
+Examples:
+dcu: dcu@2ce0000 {
+	compatible = "fsl,ls1021a-dcu";
+	reg = <0x0 0x2ce0000 0x0 0x10000>;
