+* Freescale Display Control Unit (DCU)

+Required properties:
+- compatible: Should be "fsl,vf610-dcu". Supported chips include
+ Vybrid VF610.
+- reg: Address and length of the register set for DCU.
+- interrupts: Should contain DCU interrupts.
+- clocks: From common clock binding: handle to DCU clock.
+- clock-names: From common clock binding: Shall be "dcu".
+- tcon-controller: The phandle of TCON controller.
+
+For the DCU initialization, we read data from TCON node.
+Required properties for TCON:
+- compatible: Should be "fsl,vf610-tcon". Supported chips include
+ Vybrid VF610.
+- reg: Address and length of the register set for TCON.
+- clocks: From common clock binding: handle to TCON clock.
+- clock-names: From common clock binding: Shall be "tcon".

+Examples:
+
+dcu0: dcu@40058000 {
+ compatible = "fsl,vf610-dcu";
+ reg = <0x40058000 0x1200>;
+ interrupts = <0 30 0x04>;
+ clocks = <&clks VF610_CLK_DCU0>;
+ clock-names = "dcu";
+ tcon-controller = <&tcon0>;

+ compatible = "fsl,vf610-tcon";
+ reg = <0x4003d000 0x1000>;
+ clocks = <&clks VF610_CLK_TCON0>;
