+* Omnivision OV7670 CMOS sensor
+
+The Omnivision OV7670 sensor supports multiple resolutions output, such as
+CIF, SVGA, UXGA. It also can support the YUV422/420, RGB565/555 or raw RGB
+output formats.
+
+Required Properties:
+- compatible: should be "ovti,ov7670"
+- clocks: reference to the xclk input clock.
+- clock-names: should be "xclk".
+
+Optional Properties:
+- reset-gpios: reference to the GPIO connected to the resetb pin, if any.
+  Active is low.
+- powerdown-gpios: reference to the GPIO connected to the pwdn pin, if any.
+  Active is high.
+
+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: i2c@f0018000 {
+		ov7670: camera@21 {
+			compatible = "ovti,ov7670";
+			reg = <0x21>;
+			pinctrl-names = "default";
+			pinctrl-0 = <&pinctrl_pck0_as_isi_mck &pinctrl_sensor_power &pinctrl_sensor_reset>;
+			reset-gpios = <&pioE 11 GPIO_ACTIVE_LOW>;
+			powerdown-gpios = <&pioE 13 GPIO_ACTIVE_HIGH>;
+			clocks = <&pck0>;
+			clock-names = "xclk";
+			assigned-clocks = <&pck0>;
+			assigned-clock-rates = <25000000>;
+
+			port {
+				ov7670_0: endpoint {
+					remote-endpoint = <&isi_0>;
+				};
+			};
+		};
+	};
