   1 * Omnivision 1/7.5-Inch B&W VGA CMOS Digital Image Sensor
   2
   3 The Omnivision OV7251 is a 1/7.5-Inch CMOS active pixel digital image sensor
   4 with an active array size of 640H x 480V. It is programmable through a serial
   5 I2C interface.
   6
   7 Required 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
  18 The device node shall contain one 'port' child node with a single 'endpoint'
  19 subnode for its digital output video port, in accordance with the video
  20 interface bindings defined in
  21 Documentation/devicetree/bindings/media/video-interfaces.txt.
