+Analogix ANX6345 eDP Transmitter
+--------------------------------
+
+The ANX6345 is an ultra-low power Full-HD eDP transmitter designed for
+portable devices.
+
+Required properties:
+
+ - compatible		: "analogix,anx6345"
+ - reg			: I2C address of the device
+ - reset-gpios		: Which GPIO to use for reset
+
+Optional properties:
+
+ - dvdd12-supply	: Regulator for 1.2V digital core power.
+ - dvdd25-supply	: Regulator for 2.5V digital core power.
+ - Video ports for RGB input and eDP output using the DT bindings
+   defined in [1]
+
+[1]: Documentation/devicetree/bindings/media/video-interfaces.txt
+
+Example:
+
+anx6345: anx6345@38 {
+	compatible = "analogix,anx6345";
+	reg = <0x38>;
+	reset-gpios = <&pio 3 24 GPIO_ACTIVE_HIGH>; /* PD24 */
+	dvdd25-supply = <&reg_dldo2>;
+	dvdd12-supply = <&reg_fldo1>;
+
+	ports {
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		anx6345_in: port@0 {
+			#address-cells = <1>;
+			#size-cells = <0>;
+			reg = <0>;
+			anx6345_in_tcon0: endpoint@0 {
+				reg = <0>;
+				remote-endpoint = <&tcon0_out_anx6345>;
+			};
+		};
+
+		anx6345_out: port@1 {
+			#address-cells = <1>;
+			#size-cells = <0>;
+			reg = <1>;
+
+			anx6345_out_panel: endpoint@0 {
+				reg = <0>;
+				remote-endpoint = <&panel_in_edp>;
+			};
