+Renesas Gen3 DWC HDMI TX Encoder
+================================
+
+The HDMI transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP
+with a companion PHY IP.
+
+These DT bindings follow the Synopsys DWC HDMI TX bindings defined in
+Documentation/devicetree/bindings/display/bridge/dw_hdmi.txt with the
+following device-specific properties.
+
+
+Required properties:
+
+- compatible : Shall contain one or more of
+  - "renesas,r8a774a1-hdmi" for R8A774A1 (RZ/G2M) compatible HDMI TX
+  - "renesas,r8a774b1-hdmi" for R8A774B1 (RZ/G2N) compatible HDMI TX
+  - "renesas,r8a774e1-hdmi" for R8A774E1 (RZ/G2H) compatible HDMI TX
+  - "renesas,r8a7795-hdmi" for R8A7795 (R-Car H3) compatible HDMI TX
+  - "renesas,r8a7796-hdmi" for R8A7796 (R-Car M3-W) compatible HDMI TX
+  - "renesas,r8a77961-hdmi" for R8A77961 (R-Car M3-W+) compatible HDMI TX
+  - "renesas,r8a77965-hdmi" for R8A77965 (R-Car M3-N) compatible HDMI TX
+  - "renesas,rcar-gen3-hdmi" for the generic R-Car Gen3 and RZ/G2 compatible
+			     HDMI TX
+
+    When compatible with generic versions, nodes must list the SoC-specific
+    version corresponding to the platform first, followed by the
+    family-specific version.
+
+- reg: See dw_hdmi.txt.
+- interrupts: HDMI interrupt number
+- clocks: See dw_hdmi.txt.
+- clock-names: Shall contain "iahb" and "isfr" as defined in dw_hdmi.txt.
+- ports: See dw_hdmi.txt. The DWC HDMI shall have one port numbered 0
+  corresponding to the video input of the controller and one port numbered 1
+  corresponding to its HDMI output, and one port numbered 2 corresponding to
+  sound input of the controller. Each port shall have a single endpoint.
+
+Optional properties:
+
+- power-domains: Shall reference the power domain that contains the DWC HDMI,
+  if any.
+
+
+Example:
+
+	hdmi0: hdmi@fead0000 {
+		compatible = "renesas,r8a7795-hdmi", "renesas,rcar-gen3-hdmi";
+		reg = <0 0xfead0000 0 0x10000>;
+		interrupts = <0 389 IRQ_TYPE_LEVEL_HIGH>;
+		clocks = <&cpg CPG_CORE R8A7795_CLK_S0D4>, <&cpg CPG_MOD 729>;
+		clock-names = "iahb", "isfr";
+		power-domains = <&sysc R8A7795_PD_ALWAYS_ON>;
+
+		ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+			port@0 {
+				reg = <0>;
+				dw_hdmi0_in: endpoint {
+					remote-endpoint = <&du_out_hdmi0>;
+				};
+			};
+			port@1 {
+				reg = <1>;
+				rcar_dw_hdmi0_out: endpoint {
+					remote-endpoint = <&hdmi0_con>;
+				};
+			};
+			port@2 {
+				reg = <2>;
+				rcar_dw_hdmi0_sound_in: endpoint {
+					remote-endpoint = <&hdmi_sound_out>;
+				};
+			};
+		};
+	};
+
+	hdmi0-out {
+		compatible = "hdmi-connector";
+		label = "HDMI0 OUT";
+		type = "a";
+
+		port {
+			hdmi0_con: endpoint {
+				remote-endpoint = <&rcar_dw_hdmi0_out>;
+			};
+		};
+	};
