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
|
|
- "renesas,r8a77970-lvds" for R8A77970 (R-Car V3M) 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 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 {
|
|
};
|
|
};
|
|
};
|
|
};
