+* Omnivision 1/4-Inch 5Mp CMOS Digital Image Sensor
+
+The Omnivision OV5645 is a 1/4-Inch CMOS active pixel digital image sensor with
+an active array size of 2592H x 1944V. It is programmable through a serial SCCB
+interface.
+
+Required Properties:
+- compatible: value should be "ovti,ov5645"
+- clocks: reference to the xclk clock
+- clock-names: should be "xclk"
+- assigned-clocks: reference to the xclk clock
+- assigned-clock-rates: should be "23880000"
+
+Optional Properties:
+- reset-gpios: Chip reset GPIO
+- pwdn-gpios: Chip power down GPIO
+- dovdd-supply: Chip IO regulator
+- dvdd-supply: Chip core regulator
+- avdd-supply: Chip analog regulator
+
+The device node must contain one 'port' child node for its digital output
+video port, in accordance with the video interface bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
+
+	&i2c1 {
+		...
+
+		ov5645: ov5645@78 {
+			compatible = "ovti,ov5645";
+			reg = <0x78>;
+
+			pwdn-gpios = <&gpio1 6 GPIO_ACTIVE_LOW>;
+			reset-gpios = <&gpio5 20 GPIO_ACTIVE_LOW>;
+			pinctrl-names = "default";
+			pinctrl-0 = <&camera_rear_default>;
+
+			clocks = <&clks 200>;
+			clock-names = "xclk";
+			assigned-clocks = <&clks 200>;
+			assigned-clock-rates = <23880000>;
+
+			dovdd-supply = <&camera_dovdd_1v8>;
+			avdd-supply = <&camera_avdd_2v8>;
+			dvdd-supply = <&camera_dvdd_1v2>;
+
+			port {
+				ov5645_ep: endpoint {
+					clock-lanes = <1>;
+					data-lanes = <0 2>;
+					remote-endpoint = <&csi0_ep>;
+				};
+			};
+		};
+	};
