| * 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 { |
| ... |

| |
| 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>; |
