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.

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.

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.
