+DesignWare HDMI bridge bindings
+
+Required properities:
+- compatibel: platform specific such as "fsl,imx6q-hdmi","fsl,imx6dl-hdmi"
+	      "rockchip,rk3288-dw-hdmi"
+- reg: physical base address of the controller and length
+- ddc-i2c-bus: the ddc i2c bus
+- interrupts: The interrupt number to the cpu
+
+Optional properties
+- reg-io-width: the width of the reg:1,4, default set to 1 if not present
+
+Example:
+	hdmi: hdmi@...0000 {
+		compatible = "fsl,imx6q-hdmi";
+		reg = <0x00120000 0x9000>;
+		interrupts = <0 115 0x04>;
+		gpr = <&gpr>;
+		clocks = <&clks 123>, <&clks 124>;
+		clock-names = "iahb", "isfr";
+		ddc-i2c-bus = <&i2c2>;
+
+		port@0 {
+			reg = <0>;
+
+			hdmi_mux_0: endpoint {
+				remote-endpoint = <&ipu1_di0_hdmi>;
+			};
+		};
+
+		port@1 {
+			reg = <1>;
+
+			hdmi_mux_1: endpoint {
+				remote-endpoint = <&ipu1_di1_hdmi>;
+			};
+		};
+	};
