   1 Rockchip LVDS interface
   2 ------------------
   3
   4 Required properties:
   5 - compatible: "rockchip,rk3288-lvds";
   6
   7 - reg: physical base address of the controller and length
   8         of memory mapped region.
   9 - clocks: must include clock specifiers corresponding to entries in the
  10         clock-names property.
  11 - clock-names: must contain "pclk_lvds"
  12
  13 - rockchip,grf: phandle to the general register files syscon
  14
  15 - rockchip,data-mapping: should be <LVDS_FORMAT_VESA> or  <LVDS_FORMAT_JEIDA>,
  16         This describes how the color bits are laid out in the
  17         serialized LVDS signal.
  18 - rockchip,data-width : should be <18> or <24>;
  19 - rockchip,output: should be <LVDS_OUTPUT_RGB>, <LVDS_OUTPUT_SINGLE> or
  20         <LVDS_OUTPUT_DUAL>, This describes the output face.
  21
  22 - display-timings : described by
  23         doc/devicetree/device-tree-bindings/video/display-timing.txt.
