1* Omnivision 1/7.5-Inch B&W VGA CMOS Digital Image Sensor 2 3The Omnivision OV7251 is a 1/7.5-Inch CMOS active pixel digital image sensor 4with an active array size of 640H x 480V. It is programmable through a serial 5I2C interface. 6 7Required Properties: 8- compatible: Value should be "ovti,ov7251". 9- clocks: Reference to the xclk clock. 10- clock-names: Should be "xclk". 11- clock-frequency: Frequency of the xclk clock. 12- enable-gpios: Chip enable GPIO. Polarity is GPIO_ACTIVE_HIGH. This corresponds 13 to the hardware pin XSHUTDOWN which is physically active low. 14- vdddo-supply: Chip digital IO regulator. 15- vdda-supply: Chip analog regulator. 16- vddd-supply: Chip digital core regulator. 17 18The device node shall contain one 'port' child node with a single 'endpoint' 19subnode for its digital output video port, in accordance with the video 20interface bindings defined in 21Documentation/devicetree/bindings/media/video-interfaces.txt. 22 23Example: 24 25 &i2c1 { 26 ... 27 28 ov7251: camera-sensor@60 { 29 compatible = "ovti,ov7251"; 30 reg = <0x60>; 31 32 enable-gpios = <&gpio1 6 GPIO_ACTIVE_HIGH>; 33 pinctrl-names = "default"; 34 pinctrl-0 = <&camera_bw_default>; 35 36 clocks = <&clks 200>; 37 clock-names = "xclk"; 38 clock-frequency = <24000000>; 39 40 vdddo-supply = <&camera_dovdd_1v8>; 41 vdda-supply = <&camera_avdd_2v8>; 42 vddd-supply = <&camera_dvdd_1v2>; 43 44 port { 45 ov7251_ep: endpoint { 46 clock-lanes = <1>; 47 data-lanes = <0>; 48 remote-endpoint = <&csi0_ep>; 49 }; 50 }; 51 }; 52 };
