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/device-tree-bindings/video/display-timing.txt.
