* Omnivision OV2640 CMOS sensor

The Omnivision OV2640 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,ov2640"
- clocks: reference to the xvclk input clock.
- clock-names: should be "xvclk".

Optional Properties:
- resetb-gpios: reference to the GPIO connected to the resetb pin, if any.
- pwdn-gpios: reference to the GPIO connected to the pwdn pin, if any.

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 {
		ov2640: camera@30 {
			compatible = "ovti,ov2640";
			reg = <0x30>;
			pinctrl-names = "default";
			pinctrl-0 = <&pinctrl_pck0_as_isi_mck &pinctrl_sensor_power &pinctrl_sensor_reset>;
			resetb-gpios = <&pioE 11 GPIO_ACTIVE_LOW>;
			pwdn-gpios = <&pioE 13 GPIO_ACTIVE_HIGH>;
			clocks = <&pck0>;
			clock-names = "xvclk";
			assigned-clocks = <&pck0>;
			assigned-clock-rates = <25000000>;

			port {
				ov2640_0: endpoint {
					remote-endpoint = <&isi_0>;
				};
			};
		};
	};
