* Omnivision OV7720/OV7725 CMOS sensor
|
|
The Omnivision OV7720/OV7725 sensor supports multiple resolutions output,
|
such as VGA, QVGA, and any size scaling down from CIF to 40x30. It also can
|
support the YUV422, RGB565/555/444, GRB422 or raw RGB output formats.
|
|
Required Properties:
|
- compatible: shall be one of
|
"ovti,ov7720"
|
"ovti,ov7725"
|
- clocks: reference to the xclk input clock.
|
|
Optional Properties:
|
- reset-gpios: reference to the GPIO connected to the RSTB pin which is
|
active low, if any.
|
- powerdown-gpios: reference to the GPIO connected to the PWDN pin which is
|
active high, if any.
|
|
The device node shall contain one 'port' child node with one child 'endpoint'
|
subnode for its digital output video port, in accordance with the video
|
interface bindings defined in Documentation/devicetree/bindings/media/
|
video-interfaces.txt.
|
|
Example:
|
|
&i2c0 {
|
ov772x: camera@21 {
|
compatible = "ovti,ov7725";
|
reg = <0x21>;
|
reset-gpios = <&axi_gpio_0 0 GPIO_ACTIVE_LOW>;
|
powerdown-gpios = <&axi_gpio_0 1 GPIO_ACTIVE_LOW>;
|
clocks = <&xclk>;
|
|
port {
|
ov772x_0: endpoint {
|
remote-endpoint = <&vcap1_in0>;
|
};
|
};
|
};
|
};
