+Analogix ANX7814 SlimPort (Full-HD Transmitter)
+-----------------------------------------------
+
+The ANX7814 is an ultra-low power Full-HD (1080p60) SlimPort transmitter
+designed for portable devices.
+
+Required properties:
+
+ - compatible		: "analogix,anx7814"
+ - reg			: I2C address of the device
+ - interrupt-parent	: Should be the phandle of the interrupt controller
+			  that services interrupts for this device
+ - interrupts		: Should contain the INTP interrupt
+ - hpd-gpios		: Which GPIO to use for hpd
+ - pd-gpios		: Which GPIO to use for power down
+ - reset-gpios		: Which GPIO to use for reset
+
+Optional properties:
+
+ - v10-gpios		: Which GPIO to use for V10 control.
+ - Video port for HDMI input, using the DT bindings defined in [1].
+
+[1]: Documentation/devicetree/bindings/media/video-interfaces.txt
+
+Example:
+
+	anx7814: anx7814@38 {
+		compatible = "analogix,anx7814";
+		reg = <0x38>;
+		interrupt-parent = <&gpio0>;
+		interrupts = <99 IRQ_TYPE_LEVEL_LOW>;   /* INTP */
+		hpd-gpios = <&pio 36 GPIO_ACTIVE_HIGH>;
+		pd-gpios = <&pio 33 GPIO_ACTIVE_HIGH>;
+		reset-gpios = <&pio 98 GPIO_ACTIVE_HIGH>;
+		v10-gpios = <&pio 35 GPIO_ACTIVE_HIGH>;
+		port {
+			anx7814_in: endpoint {
+				remote-endpoint = <&hdmi0_out>;
+			};
+		};
+	};
