-* 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@3c {
- compatible = "ovti,ov5645";
- reg = <0x3c>;

- reset-gpios = <&gpio5 20 GPIO_ACTIVE_LOW>;
