+Renesas R-Car LVDS Encoder
+==========================
+
+These DT bindings describe the LVDS encoder embedded in the Renesas R-Car Gen2
+and Gen3 SoCs.
+
+Required properties:
+
+- compatible : Shall contain one of
+ - "renesas,lvds-r8a7743" for R8A7790 (R-Car RZ/G1M) compatible LVDS encoders
+ - "renesas,lvds-r8a7790" for R8A7790 (R-Car H2) compatible LVDS encoders
+ - "renesas,lvds-r8a7791" for R8A7791 (R-Car M2-W) compatible LVDS encoders
+ - "renesas,lvds-r8a7793" for R8A7791 (R-Car M2-N) compatible LVDS encoders
+ - "renesas,lvds-r8a7795" for R8A7795 (R-Car H3) compatible LVDS encoders
+ - "renesas,lvds-r8a7796" 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
+
+Requires 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 input
s/parallel/RGB/, perhaps?
+- Video port 1 corresponds to the LVDS output
+
+Each port shall have a single endpoint.
+
+
+Example:
+
+ lvds0: lvds@feb90000 {
+ compatible = "renesas,lvds-r8a7790";
+ reg = <0 0xfeb90000 0 0x1c>;
+ clocks = <&cpg CPG_MOD 726>;
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ reg = <0>;
+ lvds0_in: endpoint {
+ remote-endpoint = <&du_out_lvds0>;
Err, that "du_out_lvds0" label no longer reflects reality, no?
