1 Renesas R-Car LVDS Encoder
2 ==========================
4 These DT bindings describe the LVDS encoder embedded in the Renesas R-Car
5 Gen2, R-Car Gen3 and RZ/G SoCs.
9 - compatible : Shall contain one of
10 - "renesas,r8a7743-lvds" for R8A7743 (RZ/G1M) compatible LVDS encoders
11 - "renesas,r8a774c0-lvds" for R8A774C0 (RZ/G2E) compatible LVDS encoders
12 - "renesas,r8a7790-lvds" for R8A7790 (R-Car H2) compatible LVDS encoders
13 - "renesas,r8a7791-lvds" for R8A7791 (R-Car M2-W) compatible LVDS encoders
14 - "renesas,r8a7793-lvds" for R8A7793 (R-Car M2-N) compatible LVDS encoders
15 - "renesas,r8a7795-lvds" for R8A7795 (R-Car H3) compatible LVDS encoders
16 - "renesas,r8a7796-lvds" for R8A7796 (R-Car M3-W) compatible LVDS encoders
17 - "renesas,r8a77965-lvds" for R8A77965 (R-Car M3-N) compatible LVDS encoders
18 - "renesas,r8a77970-lvds" for R8A77970 (R-Car V3M) compatible LVDS encoders
19 - "renesas,r8a77980-lvds" for R8A77980 (R-Car V3H) compatible LVDS encoders
20 - "renesas,r8a77990-lvds" for R8A77990 (R-Car E3) compatible LVDS encoders
21 - "renesas,r8a77995-lvds" for R8A77995 (R-Car D3) compatible LVDS encoders
23 - reg: Base address and length for the memory-mapped registers
24 - clocks: A list of phandles + clock-specifier pairs, one for each entry in
25 the clock-names property.
26 - clock-names: Name of the clocks. This property is model-dependent.
27 - The functional clock, which mandatory for all models, shall be listed
28 first, and shall be named "fck".
29 - On R8A77990, R8A77995 and R8A774C0, the LVDS encoder can use the EXTAL or
30 DU_DOTCLKINx clocks. Those clocks are optional. When supplied they must be
31 named "extal" and "dclkin.x" respectively, with "x" being the DU_DOTCLKIN
33 - When the clocks property only contains the functional clock, the
34 clock-names property may be omitted.
35 - resets: A phandle + reset specifier for the module reset
39 The LVDS encoder has two video ports. Their connections are modelled using the
40 OF graph bindings specified in Documentation/devicetree/bindings/graph.txt.
42 - Video port 0 corresponds to the parallel RGB input
43 - Video port 1 corresponds to the LVDS output
45 Each port shall have a single endpoint.
