* Omnivision ov5648 MIPI CSI-2 sensor

Required Properties:
- compatible: should be "ovti,ov5648"
- clocks: reference to the 24M xvclk input clock.
- clock-names: should be "xvclk".
- dovdd-supply: Digital I/O voltage supply, 1.8 volts
- avdd-supply: Analog voltage supply, 2.8 volts
- dvdd-supply: Digital core voltage supply, 1.5 volts
- reset-gpios: Low active reset gpio
- powerdown-gpios: Low active powerdown 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:
&i2c2 {
	status = "okay";

	ov5648: ov5648@36 {
		status = "okay";
		compatible = "ovti,ov5648";
		reg = <0x36>;
		clocks = <&cru SCLK_CIF_OUT>;
		clock-names = "xvclk";

		avdd-supply = <&vcc2v8_dvp>;
		dovdd-supply = <&vcc1v8_dvp>;
		dvdd-supply = <&vdd1v5_dvp>;
		pinctrl-names = "rockchip,camera_default";
		pinctrl-0 = <&cif_clkout_m0>;
		reset-gpios = <&gpio2 5 GPIO_ACTIVE_LOW>;
		pwdn-gpios = <&gpio2 13 GPIO_ACTIVE_LOW>;
		rockchip,camera-module-index = <0>;
		rockchip,camera-module-facing = "back";
		rockchip,camera-module-name = "CameraKing";
		rockchip,camera-module-lens-name = "CHT-842B-MD";
		port {
			ucam_out: endpoint {
				remote-endpoint = <&mipi_in_ucam>;
				data-lanes = <1 2>;
			};
		};
	};
};
