* Omnivision OV2685 MIPI CSI-2 sensor

Required Properties:
- compatible: should be "ovti,ov2685"
- clocks: reference to the 24M xvclk input clock.
- clock-names: should be "xvclk".
- avdd-supply: Analog voltage supply, 2.8 volts
- dvdd-supply: Digital core voltage supply, 1.2 volts
- reset-gpios: Low active reset gpio

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:
	ucam: camera-sensor@3c {
		compatible = "ovti,ov2685";
		reg = <0x3c>;
		pinctrl-names = "default";
		pinctrl-0 = <&clk_24m_cam>;

		clocks = <&cru SCLK_TESTCLKOUT1>;
		clock-names = "xvclk";

		avdd-supply = <&pp2800_cam>;
		dovdd-supply = <&pp1800>;
		reset-gpios = <&gpio2 3 GPIO_ACTIVE_LOW>;

		port {
			ucam_out: endpoint {
				remote-endpoint = <&mipi_in_ucam>;
				data-lanes = <1>;
			};
		};
	};
