+* 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.
+- display: The phandle to display node.
+
+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".
+
+* display node
+
+Required properties:
+- bits-per-pixel: <24> for RGB888.
+
+Required sub-node:
+- display-timings: Refer to binding doc display-timing.txt for details.
+
+Examples:
