1* Omnivision OV2640 CMOS sensor
2
3The Omnivision OV2640 sensor supports multiple resolutions output, such as
4CIF, SVGA, UXGA. It also can support the YUV422/420, RGB565/555 or raw RGB
5output formats.
6
7Required Properties:
8- compatible: should be "ovti,ov2640"
9- clocks: reference to the xvclk input clock.
10- clock-names: should be "xvclk".
11
12Optional Properties:
13- resetb-gpios: reference to the GPIO connected to the resetb pin, if any.
14- pwdn-gpios: reference to the GPIO connected to the pwdn pin, if any.
15
16The device node must contain one 'port' child node for its digital output
17video port, in accordance with the video interface bindings defined in
18Documentation/devicetree/bindings/media/video-interfaces.txt.
