+Renesas R-Car LVDS Encoder
+==========================

+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

+
+- 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.
