[PATCH v2 0/8] libcamera: Add swstats_cpu::processFrame() and atomisp pipeline handler

[Hans de Goede]

Hi All,

Here is v2 of my patch series adding support to the swstats_cpu code
to process a whole frame in one go (also useful for the GPU-ISP work)
and adding a new pipeline handler for the atomisp.

Original v1 series:
https://patchwork.libcamera.org/cover/21798/

Later rebased resend of just the swstats_cpu::processFrame() changes:
https://patchwork.libcamera.org/cover/22186/

Changes in v2:
- Rebase on top of latest master
- Fix the lack of doxygen documentation
- Reworked "[PATCH v2 7/8] libcamera: ipa_manager: createIPA: Allow
  matching by IPA name instead of by pipeline" this probably is the most
  controversial change in this series
- Modify atomisp pipeline handler to also work with sensors where there
  is an ISP on the sensor which the driver registers as a separate
  v4l2-subdev like the MT9M114 sensor driver

Patches 1-4 have already been reviewed by both Kieran and Milan.

Please review patches 5-8.

This has already successfully passed the CI, see:
https://gitlab.freedesktop.org/camera/libcamera-softisp/-/commits/atomisp-v2/

Regards,

Hans
