* Omnivision 1/4-Inch 5Mp CMOS Digital Image Sensor
|
|
The Omnivision OV5645 is a 1/4-Inch CMOS active pixel digital image sensor with
|
an active array size of 2592H x 1944V. It is programmable through a serial I2C
|
interface.
|
|
Required Properties:
|
- compatible: Value should be "ovti,ov5645".
|
- 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 PWDNB which is physically active low.
|
- reset-gpios: Chip reset GPIO. Polarity is GPIO_ACTIVE_LOW. This corresponds to
|
the hardware pin RESETB.
|
- vdddo-supply: Chip digital IO regulator.
|
- vdda-supply: Chip analog regulator.
|
- vddd-supply: Chip digital core regulator.
|
|
The device node must contain one 'port' child node for its digital output
|
video port, in accordance with the video interface bindings defined in
|
Documentation/devicetree/bindings/media/video-interfaces.txt.
