* Omnivision 1/7.5-Inch B&W VGA CMOS Digital Image Sensor The Omnivision OV7251 is a 1/7.5-Inch CMOS active pixel digital image sensor with an active array size of 640H x 480V. It is programmable through a serial I2C interface. Required Properties: - compatible: Value should be "ovti,ov7251". - clocks: Reference to the xclk clock. - clock-names: Should be "xclk". - clock-frequency: Frequency of the xclk clock. - enable-gpios: Chip enable GPIO. Polarity is GPIO_ACTIVE_HIGH. This corresponds to the hardware pin XSHUTDOWN which is physically active low. - vdddo-supply: Chip digital IO regulator. - vdda-supply: Chip analog regulator. - vddd-supply: Chip digital core regulator. The device node shall contain one 'port' child node with a single 'endpoint' subnode for its digital output video port, in accordance with the video interface bindings defined in Documentation/devicetree/bindings/media/video-interfaces.txt. Example: &i2c1 { ... ov7251: camera-sensor@60 { compatible = "ovti,ov7251"; reg = <0x60>; enable-gpios = <&gpio1 6 GPIO_ACTIVE_HIGH>; pinctrl-names = "default"; pinctrl-0 = <&camera_bw_default>; clocks = <&clks 200>; clock-names = "xclk"; clock-frequency = <24000000>; vdddo-supply = <&camera_dovdd_1v8>; vdda-supply = <&camera_avdd_2v8>; vddd-supply = <&camera_dvdd_1v2>; port { ov7251_ep: endpoint { clock-lanes = <1>; data-lanes = <0>; remote-endpoint = <&csi0_ep>; }; }; }; };
