+* Currus Logic CLPS711X Framebuffer
+
+Required properties:
+- compatible: Shall contain "cirrus,clps711x-fb".
+- reg : Physical base address and length of the controller's registers +
+ location and size of the framebuffer memory.
+- clocks : phandle + clock specifier pair of the FB reference clock.
+- display : phandle to a display node as described in
+ Documentation/devicetree/bindings/video/display-timing.txt.
+ Additionally, the display node has to define properties:
+ - bits-per-pixel: Bits per pixel.
+ - ac-prescale : LCD AC bias frequency. This frequency is the required
+ AC bias frequency for a given manufacturer's LCD plate.
+ - cmap-invert : Invert the color levels (Optional).
+
+Optional properties:
+- lcd-supply: Regulator for LCD supply voltage.
+
+Example:
+ fb: fb@800002c0 {
+ compatible = "cirrus,ep7312-fb", "cirrus,clps711x-fb";
+ reg = <0x800002c0 0xd44>, <0x60000000 0xc000>;
+ clocks = <&clks 2>;
+ lcd-supply = <&reg5v0>;
+ display = <&display>;
+ };
+
+ display: display {
+ model = "320x240x4";
+ native-mode = <&timing0>;
+ bits-per-pixel = <4>;
+ ac-prescale = <17>;
+
+ display-timings {
+ timing0: 320x240 {
+ hactive = <320>;
+ hback-porch = <0>;
+ hfront-porch = <0>;
+ hsync-len = <0>;
+ vactive = <240>;
+ vback-porch = <0>;
