+THine Electronics THC63LVD1024 LVDS receiver
+--------------------------------------------
+
+The THC63LVD1024 is an LVDS receiver designed to convert multiple LVDS streams
+to digital CMOS/TTL parallel data.
+
+Required properties:
+- compatible: Shall be one of the following:
+  "thine,thc63lvd1024",
+  "lvds-decoder"
+
+Optional properties:
+- supply-vcc: Power supply for TTL output and digital circuitry
+- supply-cvcc: Power supply for TTL CLOCKOUT signal
+- supply-lvcc: Power supply for LVDS inputs
+- supply-pvcc: Power supply for PLL circuitry
+- pwnd-gpio: Power down GPIO signal. Active low.
+- oe-gpio: Output enable GPIO signal. Active high.
+
+The THC63LVD1024 has two video ports, whose connections are modeled according
+to OF graph bindings specified by Documentation/devicetree/bindings/graph.txt
+
+- Port@0: LVDS input port
+- Port@1: Digital CMOS/TTL parallel output
+
+Example:
+-------
+
+	lvds_decoder: decoder-0 {
+		compatible = "thine,thc63lvd1024";
+
+		vcc-supply = <&reg_lvds_vcc>;
+		lvcc-supply = <&reg_lvds_lvcc>;
+
+		pwdn-gpio = <&gpio4 15 GPIO_ACTIVE_LOW>;
+
+		ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			port@0 {
+				reg = <0>;
+
+				lvds_dec_in: endpoint {
+					remote-endpoint = <&lvds_out>;
+				};
+			};
+
+			port@1{
+				reg = <1>;
+
+				lvds_dec_out: endpoint {
+					remote-endpoint = <&adv7511_in>;
+				};
+
+			};
+
+		};
+	};
