+Omnivision OV5647 raw image sensor
+---------------------------------
+
+OV5647 is a raw image sensor with MIPI CSI-2 and CCP2 image data interfaces
+and CCI (I2C compatible) control bus.
+
+Required properties:
+
+- compatible		: "ovti,ov5647".
+- reg			: I2C slave address of the sensor.
+- clocks		: Reference to the xclk clock.
+
+The common video interfaces bindings (see video-interfaces.txt) should be
+used to specify link to the image data receiver. The OV5647 device
+node should contain one 'port' child node with an 'endpoint' subnode.
+
+Endpoint node mandatory properties:
+
+- remote-endpoint: A phandle to the bus receiver's endpoint node.
+
+Example:
+
+	i2c@2000 {
+		...
+		ov: camera@36 {
+			compatible = "ovti,ov5647";
+			reg = <0x36>;
+			clocks = <&camera_clk>;
+			port {
+				camera_1: endpoint {
+					remote-endpoint = <&csi1_ep1>;
+				};
+			};
+		};
+	};
