* Omnivision OV2640 CMOS sensor
|
|
|
|
The Omnivision OV2640 sensor support multiple resolutions output, such as
|
|
CIF, SVGA, UXGA. It also can support YUV422/420, RGB565/555 or raw RGB
|
|
output format.
|
|
|
|
Required Properties:
|
|
- compatible: should be "ovti,ov2640"
|
|
- clocks: reference to the xvclk input clock.
|
|
- clock-names: should be "xvclk".
|
|
|
|
Optional Properties:
|
|
- resetb-gpios: reference to the GPIO connected to the resetb pin, if any.
|
|
- pwdn-gpios: reference to the GPIO connected to the pwdn pin, if any.
|
|
|
|
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.
