* BF3925 1/5-Inch 2Mp SOC Camera

The BYD BF3925 is a 1/5-inch SOC camera, with an active array size of
1616H x 1216V. It is programmable through a SCCB. The BF3925 sensor supports
multiple resolutions output, such as UXGA, SVGA. It also can support
YUV422 or raw RGB output formats.

Required Properties:
- compatible: Must be "byd,bf3925"
- reg: I2C slave address
- clocks: reference to the xvclk input clock.
- clock-names: should be "xvclk".
- dovdd-supply: Digital I/O voltage supply, 1.7~3.1 volts
- avdd-supply: Analog voltage supply, 2.8 volts
- dvdd-supply: Digital core voltage supply, 1.8 volts
- reset-gpios: Low active reset gpio
- powerdown-gpios: HIGH 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";

	bf3925: bf3925@6e {
		status = "okay";
		compatible = "byd,bf3925";
		reg = <0x6e>;
		clocks = <&cru SCLK_CIF_OUT>;
		clock-names = "xvclk";

		avdd-supply = <&vcc2v8_dvp>;
		dovdd-supply = <&vcc1v8_dvp>;
		dvdd-supply = <&vdd1v8_dvp>;
		pinctrl-names = "default";
		pinctrl-0 = <&cif_clkout_m0>;
		reset-gpios = <&gpio2 5 GPIO_ACTIVE_LOW>;
		pwdn-gpios = <&gpio2 13 GPIO_ACTIVE_HIGH>;
		rockchip,camera-module-index = <0>;
		rockchip,camera-module-facing = "back";
		rockchip,camera-module-name = "default";
		rockchip,camera-module-lens-name = "default";

		port {
			bf3925_out: endpoint {
				remote-endpoint = <&dvp_in_bcam>;
			};
		};
	};
};
