This is a quite large renaming to consolidate display related bindings into a single "display" directory from various scattered locations of video, drm, gpu, fb, mipi, and panel. The prior location was somewhat based on the Linux driver location, but bindings should be independent of that.

* 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/display/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";
|
|
