* 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.
Example:
&i2c1 {
...
ov5645: ov5645@78 {
compatible = "ovti,ov5645";
reg = <0x78>;
enable-gpios = <&gpio1 6 GPIO_ACTIVE_HIGH>;
reset-gpios = <&gpio5 20 GPIO_ACTIVE_LOW>;
pinctrl-names = "default";
pinctrl-0 = <&camera_rear_default>;
clocks = <&clks 200>;
clock-names = "xclk";
clock-frequency = <23880000>;
vdddo-supply = <&camera_dovdd_1v8>;
vdda-supply = <&camera_avdd_2v8>;
vddd-supply = <&camera_dvdd_1v2>;
port {
ov5645_ep: endpoint {
clock-lanes = <1>;
data-lanes = <0 2>;
remote-endpoint = <&csi0_ep>;
};
};
};
};
