* Sony IMX323 DVP sensor

Required Properties:
- compatible: should be "sony,imx323"
- clocks: reference to the 37.125M 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, 1.2 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:
&i2c3: imx323@1a {
	compatible = "sony,imx323";
	reg = <0x1a>;
	clocks = <&cru SCLK_CIF_OUT>;
	clock-names = "xvclk";
	avdd-supply = <&vcc2v8_dvp>;
	dovdd-supply = <&vcc1v8_dvp>;
	dvdd-supply = <&vdd1v5_dvp>;
	pwdn-gpios = <&gpio2 RK_PC4 GPIO_ACTIVE_HIGH>;
	reset-gpios = <&gpio2 RK_PC5 GPIO_ACTIVE_HIGH>;
	pinctrl-names = "default";
	pinctrl-0 = <&dvp_d0d1_m0 &dvp_d2d9_m0
		&dvp_d10d11_m0 &cif_clkout_m0>;
	port {
		imx323_out: endpoint {
			remote-endpoint = <&isp0_dvp_in>;
		};
	};
};
