| 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. |
| 24 | |
