[libcamera-devel] [PATCH v3 5/6] libcamera: sensor: Add OV5670 camera sensor

[Jacopo Mondi]

Add OV5670CameraSensor class to handle Omnivision OV5670 image sensor
and register it to the camera sensor factory and initialize its pixel
array properties by overriding CameraSensor::initProperties() method.

Signed-off-by: Jacopo Mondi <jacopo at jmondi.org>

---
v2 -> v3:
- Squash class introduction and patches registration
- Update to use the new properties names
