| +Renesas R-Car LVDS Encoder |
| +========================== |
| + |
| +These DT bindings describe the LVDS encoder embedded in the Renesas R-Car |
| +Gen2, R-Car Gen3 and RZ/G SoCs. |
| + |
| +Required properties: |
| + |
| +- compatible : Shall contain one of |
| + - "renesas,r8a7743-lvds" for R8A7743 (RZ/G1M) compatible LVDS encoders |
| + - "renesas,r8a7790-lvds" for R8A7790 (R-Car H2) compatible LVDS encoders |
| + - "renesas,r8a7791-lvds" for R8A7791 (R-Car M2-W) compatible LVDS encoders |
| + - "renesas,r8a7793-lvds" for R8A7793 (R-Car M2-N) compatible LVDS encoders |
| + - "renesas,r8a7795-lvds" for R8A7795 (R-Car H3) compatible LVDS encoders |
| + - "renesas,r8a7796-lvds" for R8A7796 (R-Car M3-W) compatible LVDS encoders |
| + |
| +- reg: Base address and length for the memory-mapped registers |
| +- clocks: A phandle + clock-specifier pair for the functional clock |
| +- resets: A phandle + reset specifier for the module reset |
| + |
| +Required nodes: |
| + |
| +The LVDS encoder has two video ports. Their connections are modelled using the |
| +OF graph bindings specified in Documentation/devicetree/bindings/graph.txt. |
| + |
| +- Video port 0 corresponds to the parallel RGB input |
| +- Video port 1 corresponds to the LVDS output |
| + |
| +Each port shall have a single endpoint. |
| + |
| + |
| +Example: |
| + |
| + lvds0: lvds@feb90000 { |
| + compatible = "renesas,r8a7790-lvds"; |
| + reg = <0 0xfeb90000 0 0x1c>; |
| + clocks = <&cpg CPG_MOD 726>; |
| + resets = <&cpg 726>; |
| + |
| + ports { |
| + #address-cells = <1>; |
| + #size-cells = <0>; |
| + |
| + port@0 { |
| + reg = <0>; |
| + lvds0_in: endpoint { |
| + remote-endpoint = <&du_out_lvds0>; |
| + }; |
| + }; |
| + port@1 { |
| + reg = <1>; |
| + lvds0_out: endpoint { |
| + }; |
| + }; |
| + }; |
| + }; |
