   1 Renesas R-Car LVDS Encoder
   2 ==========================
   3
   4 These DT bindings describe the LVDS encoder embedded in the Renesas R-Car
   5 Gen2, R-Car Gen3 and RZ/G SoCs.
   6
   7 Required properties:
   8
   9 - compatible : Shall contain one of
  10   - "renesas,r8a7743-lvds" for R8A7743 (RZ/G1M) compatible LVDS encoders
  11   - "renesas,r8a7790-lvds" for R8A7790 (R-Car H2) compatible LVDS encoders
  12   - "renesas,r8a7791-lvds" for R8A7791 (R-Car M2-W) compatible LVDS encoders
  13   - "renesas,r8a7793-lvds" for R8A7793 (R-Car M2-N) compatible LVDS encoders
  14   - "renesas,r8a7795-lvds" for R8A7795 (R-Car H3) compatible LVDS encoders
  15   - "renesas,r8a7796-lvds" for R8A7796 (R-Car M3-W) compatible LVDS encoders
  16   - "renesas,r8a77970-lvds" for R8A77970 (R-Car V3M) compatible LVDS encoders
  17   - "renesas,r8a77995-lvds" for R8A77995 (R-Car D3) compatible LVDS encoders
  18
  19 - reg: Base address and length for the memory-mapped registers
  20 - clocks: A phandle + clock-specifier pair for the functional clock
  21 - resets: A phandle + reset specifier for the module reset
  22
  23 Required nodes:
  24
  25 The LVDS encoder has two video ports. Their connections are modelled using the
  26 OF graph bindings specified in Documentation/devicetree/bindings/graph.txt.
  27
  28 - Video port 0 corresponds to the parallel RGB input
  29 - Video port 1 corresponds to the LVDS output
  30
  31 Each port shall have a single endpoint.

  34 Example:
  35
  36         lvds0: lvds@feb90000 {
  37                 compatible = "renesas,r8a7790-lvds";
  38                 reg = <0 0xfeb90000 0 0x1c>;
  39                 clocks = <&cpg CPG_MOD 726>;
  40                 resets = <&cpg 726>;
  41
  42                 ports {
  43                         #address-cells = <1>;
  44                         #size-cells = <0>;
  45
  46                         port@0 {
  47                                 reg = <0>;
  48                                 lvds0_in: endpoint {
  49                                         remote-endpoint = <&du_out_lvds0>;
  50                                 };
  51                         };
  52                         port@1 {
  53                                 reg = <1>;
  54                                 lvds0_out: endpoint {
  55                                 };
  56                         };
  57                 };
  58         };
