[libcamera-devel,v3,00/23] Internal controls, sensor delays and IPA rework

16458 mbox series

Based on the previous v2, this new version reworks slightly the first part
of the series and on top, removes usage of V4L2 controls from the IPA.

The logical sequence of patches is:

- Introduce internal controls
- Create src/libcamera/camera_sensor
- Introduce sensor control delays
- Move delayed controls in CameraSensor
- Make the CameraSensor control interface use libcamera controls
- Make the IPA module use libcamera controls
- Similar adjustments to the CameraLens class

This work is only performed on IPU3, RkISP1 should be similarly reworked after
the work here has been validated.
