* Omnivision 1/7.5-Inch B&W VGA CMOS Digital Image Sensor
|
|
The Omnivision OV7251 is a 1/7.5-Inch CMOS active pixel digital image sensor
|
with an active array size of 640H x 480V. It is programmable through a serial
|
I2C interface.
|
|
Required Properties:
|
- compatible: Value should be "ovti,ov7251".
|
- 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 XSHUTDOWN which is physically active low.
|
- vdddo-supply: Chip digital IO regulator.
|
- vdda-supply: Chip analog regulator.
|
- vddd-supply: Chip digital core regulator.
|
|
The device node shall contain one 'port' child node with a single '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:
|
|
&i2c1 {
|
...
|
|
ov7251: camera-sensor@60 {
|
compatible = "ovti,ov7251";
|
reg = <0x60>;
|
|
enable-gpios = <&gpio1 6 GPIO_ACTIVE_HIGH>;
|
pinctrl-names = "default";
|
pinctrl-0 = <&camera_bw_default>;
|
|
clocks = <&clks 200>;
|
clock-names = "xclk";
|
clock-frequency = <24000000>;
|
|
vdddo-supply = <&camera_dovdd_1v8>;
|
vdda-supply = <&camera_avdd_2v8>;
|
vddd-supply = <&camera_dvdd_1v2>;
|
|
port {
|
ov7251_ep: endpoint {
|
clock-lanes = <1>;
|
data-lanes = <0>;
|
remote-endpoint = <&csi0_ep>;
|
};
