* Aptina AR0144 MIPI sensor

Required Properties:
- compatible: should be "aptina,ar0144"
- clocks: reference to the 24M xvclk input clock.
- clock-names: should be "xvclk".
- dovdd-supply: Digital I/O voltage supply, 1.8/2.8 volts
- 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:
ar0144: ar0144@10 {
	compatible = "aptina,ar0144";
	status = "okay";
	reg = <0x10>;
	clocks = <&cru SCLK_CIF_OUT>;
	clock-names = "xvclk";

	//conflict with csi-ctl-gpios
	reset-gpios = <&gpio4 26 GPIO_ACTIVE_LOW>;
	pwdn-gpios = <&gpio4 25 GPIO_ACTIVE_HIGH>;
	pinctrl-names = "rockchip,camera_default";
	pinctrl-0 = <&cif_clkout>;
	rockchip,camera-module-index = <0>;
	rockchip,camera-module-facing = "back";
	rockchip,camera-module-name = "default";
	rockchip,camera-module-lens-name = "default";
	port {
		ucam_out3: endpoint {
			remote-endpoint = <&mipi_in_ucam3>;
			data-lanes = <1>;
		};
	};
};
