[libcamera-devel] [RFC PATCH 0/3] IPU3: Tweak sensor format selection

[Umang Jain]

Different IPU3 platforms have different constraints that require certain
tweaking on the policy on how libcamera determines best sensor format.
To address these contraints, we need to drop CameraSensor::getFormat()
and have IPU3 specific sensor format selector member function.

Patch 1/3 and 2/3 prepares the base to introduce new policy on
selection. Patch 3/3 is the crux of the change, meant to address
constraints faced on Nautilus and Soraka.

This is a RFC where only preliminary testing have been done.
Extensive testing and further discussions are still under-way.

  libcamera: base: camera_sensor: Expose sensor's formats map
  ipu3: cio2: Replicate CameraSensor::getFormats() to a member function
  ipu3: cio2: Customize sensor format selection logic
