* Omnivision OV5640 MIPI CSI-2 sensor
|
||
|
|
|
||
|
|
Required Properties:
|
||
|
|
- compatible: should be "ovti,ov5640"
|
||
|
|
- clocks: reference to the xclk input clock.
|
||
|
|
- clock-names: should be "xclk".
|
||
|
|
- DOVDD-supply: Digital I/O voltage supply, 1.8 volts
|
||
|
|
- AVDD-supply: Analog voltage supply, 2.8 volts
|
||
|
|
- DVDD-supply: Digital core voltage supply, 1.5 volts
|
||
|
|
|
||
|
|
Optional Properties:
|
||
|
|
- reset-gpios: reference to the GPIO connected to the reset pin, if any.
|
||
|
|
This is an active low signal to the OV5640.
|
||
|
|
- powerdown-gpios: reference to the GPIO connected to the powerdown pin,
|
||
|
|
if any. This is an active high signal to the OV5640.
|
||
|
|
|
||
|
|
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.
