Rockchip LVDS interface
|
||
|
|
------------------
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: "rockchip,rk3288-lvds";
|
||
|
|
|
||
|
|
- reg: physical base address of the controller and length
|
||
|
|
of memory mapped region.
|
||
|
|
- clocks: must include clock specifiers corresponding to entries in the
|
||
|
|
clock-names property.
|
||
|
|
- clock-names: must contain "pclk_lvds"
|
||
|
|
|
||
|
|
- rockchip,grf: phandle to the general register files syscon
|
||
|
|
|
||
|
|
- rockchip,data-mapping: should be <LVDS_FORMAT_VESA> or <LVDS_FORMAT_JEIDA>,
|
||
|
|
This describes how the color bits are laid out in the
|
||
|
|
serialized LVDS signal.
|
||
|
|
- rockchip,data-width : should be <18> or <24>;
|
||
|
|
- rockchip,output: should be <LVDS_OUTPUT_RGB>, <LVDS_OUTPUT_SINGLE> or
|
||
|
|
<LVDS_OUTPUT_DUAL>, This describes the output face.
|
||
|
|
|
||
|
|
- display-timings : described by
|
||
|
|
doc/devicetree/device-tree-bindings/video/display-timing.txt.
|
||
|
