display-timing, it is ignored.

* Currus Logic CLPS711X Framebuffer
Required properties:
- compatible: Shall contain "cirrus,ep7209-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/display/panel/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,ep7209-fb";
reg = <0x800002c0 0xd44>, <0x60000000 0xc000>;
clocks = <&clks 2>;
lcd-supply = <&reg5v0>;
display = <&display>;
};
display: display {
model = "320x240x4";
bits-per-pixel = <4>;
ac-prescale = <17>;
display-timings {
native-mode = <&timing0>;
timing0: 320x240 {
