-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,r8a7744-lvds" for R8A7744 (RZ/G1N) compatible LVDS encoders
- - "renesas,r8a774a1-lvds" for R8A774A1 (RZ/G2M) compatible LVDS encoders
- - "renesas,r8a774b1-lvds" for R8A774B1 (RZ/G2N) compatible LVDS encoders
- - "renesas,r8a774c0-lvds" for R8A774C0 (RZ/G2E) 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
- - "renesas,r8a77965-lvds" for R8A77965 (R-Car M3-N) compatible LVDS encoders
- - "renesas,r8a77970-lvds" for R8A77970 (R-Car V3M) compatible LVDS encoders
- - "renesas,r8a77980-lvds" for R8A77980 (R-Car V3H) compatible LVDS encoders
- - "renesas,r8a77990-lvds" for R8A77990 (R-Car E3) compatible LVDS encoders
- - "renesas,r8a77995-lvds" for R8A77995 (R-Car D3) compatible LVDS encoders
-
-- reg: Base address and length for the memory-mapped registers
-- clocks: A list of phandles + clock-specifier pairs, one for each entry in
- the clock-names property.
-- clock-names: Name of the clocks. This property is model-dependent.
- - The functional clock, which mandatory for all models, shall be listed
- first, and shall be named "fck".
- - On R8A77990, R8A77995 and R8A774C0, the LVDS encoder can use the EXTAL or
- DU_DOTCLKINx clocks. Those clocks are optional. When supplied they must be
- named "extal" and "dclkin.x" respectively, with "x" being the DU_DOTCLKIN
- numerical index.
- - When the clocks property only contains the functional clock, the
- clock-names property may be omitted.
-- 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.
-
-Optional properties:
-
-- renesas,companion : phandle to the companion LVDS encoder. This property is
- mandatory for the first LVDS encoder on D3 and E3 SoCs, and shall point to
- the second encoder to be used as a companion in dual-link mode. It shall not
- be set for any other LVDS encoder.
-
-
-Example:
-
- lvds0: lvds@feb90000 {
- compatible = "renesas,r8a77990-lvds";
- reg = <0 0xfeb90000 0 0x20>;
- clocks = <&cpg CPG_MOD 727>;
- power-domains = <&sysc R8A77990_PD_ALWAYS_ON>;
- resets = <&cpg 727>;
-
- renesas,companion = <&lvds1>;
-
- 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 {
- };
- };
- };
- };
