* Omnivision OV9650/OV9652 CMOS sensor

Required Properties:
- compatible: shall be one of
	"ovti,ov9650"
	"ovti,ov9652"
- clocks: reference to the xvclk input clock.

Optional Properties:
- reset-gpios: reference to the GPIO connected to the resetb pin, if any.
  Active is high.
- powerdown-gpios: reference to the GPIO connected to the pwdn pin, if any.
  Active is high.

The device node shall contain one 'port' child node with one child 'endpoint'
subnode for its digital output video port, in accordance with the video
interface bindings defined in Documentation/devicetree/bindings/media/
video-interfaces.txt.

Example:

&i2c0 {
	ov9650: camera@30 {
		compatible = "ovti,ov9650";
		reg = <0x30>;
		reset-gpios = <&axi_gpio_0 0 GPIO_ACTIVE_HIGH>;
		powerdown-gpios = <&axi_gpio_0 1 GPIO_ACTIVE_HIGH>;
		clocks = <&xclk>;

		port {
			ov9650_0: endpoint {
				remote-endpoint = <&vcap1_in0>;
			};
		};
	};
};
