Kernel-4.18.0-80.el8_ov5645

• 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>;

        vdda-supply = <&camera_avdd_2v8>;
        vddd-supply = <&camera_dvdd_1v2>;
