+
+The ANX7688 is a single-chip mobile transmitter to support 4K 60 frames per
+second (4096x2160p60) or FHD 120 frames per second (1920x1080p120) video
+resolution from a smartphone or tablet with full function USB-C.
+
+This binding only describes the HDMI to DP display bridge.
+
+Required properties:
+
+ - compatible          : "analogix,anx7688"
+ - reg                 : I2C address of the device (fixed at 0x2c)
+
+Optional properties:
+
+ - Video port for HDMI input, using the DT bindings defined in [1].
+
+[1]: Documentation/devicetree/bindings/media/video-interfaces.txt
+
+Example:
+
+	anx7688: anx7688@2c {
+		compatible = "analogix,anx7688";
+		reg = <0x2c>;
+
+		port {
+			anx7688_in: endpoint {
+				remote-endpoint = <&hdmi0_out>;
+			};
+		};
+	};
