1* Omnivision 1/4-Inch 5Mp CMOS Digital Image Sensor
2
3The Omnivision OV5645 is a 1/4-Inch CMOS active pixel digital image sensor with
4an active array size of 2592H x 1944V. It is programmable through a serial I2C
5interface.

7Required Properties:
8- compatible: Value should be "ovti,ov5645".
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 PWDNB which is physically active low.
14- reset-gpios: Chip reset GPIO. Polarity is GPIO_ACTIVE_LOW. This corresponds to
15  the hardware pin RESETB.
16- vdddo-supply: Chip digital IO regulator.
17- vdda-supply: Chip analog regulator.
18- vddd-supply: Chip digital core regulator.

20The device node must contain one 'port' child node for its digital output
21video port, in accordance with the video interface bindings defined in
22Documentation/devicetree/bindings/media/video-interfaces.txt.
