+* Freescale Simple Display Controller FB Driver
+
+=== For dcfb node ===
+Required properties:
+- compatible: Should be one of "fsl,ls1021a-dcfb".
+- reg: Address and length of the register set for dcfb.
+- clocks: From common clock binding: handle to dcfb clock.
+- clock-names: From common clock binding: Shall be "dcfb".
+- display: The phandle to display node.
+
+Optional properties:
+- scfg-controller: The phandle of scfg node.
+
+=== For display sub-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:
+dcfb: dcfb@2ce0000 {
+ compatible = "fsl,ls1021a-dcfb";
+ reg = <0x0 0x2ce0000 0x0 0x10000>;

+ clock-names = "dcfb";
+ scfg-controller = <&scfg>;
+ display = <&display>;
+
+ display: display@0 {
+ bits-per-pixel = <24>;
+
+ display-timings {
+ native-mode = <&timing0>;
+ timing0: nl4827hc19 {
+ clock-frequency = <10870000>;
+ hactive = <480>;
+ vactive = <272>;
+ hback-porch = <2>;
