+Thine Electronics THC63LVD1024 LVDS decoder
+-------------------------------------------
+
+The THC63LVD1024 is a dual link LVDS receiver designed to convert LVDS streams
+to parallel data outputs. The chip supports single/dual input/output modes,
+handling up to two LVDS input streams and up to two digital CMOS/TTL outputs.
+
+Single or dual operation mode, output data mapping and DDR output modes are
+configured through input signals and the chip does not expose any control bus.
+
+Required properties:
+- compatible: Shall be "thine,thc63lvd1024"
+- vcc-supply: Power supply for TTL output, TTL CLOCKOUT signal, LVDS input,
+  PPL and digital circuitry
+
+Optional properties:
+- powerdown-gpios: Power down GPIO signal, pin name "/PDWN". Active low
+- oe-gpios: Output enable GPIO signal, pin name "OE". Active high
+
+The THC63LVD1024 video port connections are modeled according
+to OF graph bindings specified by Documentation/devicetree/bindings/graph.txt
+
+Required video port nodes:
+- port@0: First LVDS input port
+- port@2: First digital CMOS/TTL parallel output
+
+Optional video port nodes:
+- port@1: Second LVDS input port
+- port@3: Second digital CMOS/TTL parallel output
+
+Example:
+--------
+
+	thc63lvd1024: lvds-decoder {
+		compatible = "thine,thc63lvd1024";
+
+		vcc-supply = <&reg_lvds_vcc>;
+		powerdown-gpios = <&gpio4 15 GPIO_ACTIVE_LOW>;
+
+		ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			port@0 {
+				reg = <0>;
+
+				lvds_dec_in_0: endpoint {
+					remote-endpoint = <&lvds_out>;
+				};
+			};
+
+			port@2{
+				reg = <2>;
+
+				lvds_dec_out_2: endpoint {
+					remote-endpoint = <&adv7511_in>;
+				};
+			};
+		};
+	};
