[PATCH v1 0/5] Pre Raspberry Pi 5 support changes

[Naushir Patuck]

Hi all,

This series adds some preliminary changes to libcamera for Raspberry Pi 5
support.  The patches for the Pi 5 pipeline handler and IPA will be sent in
another series.  However, these patches can be merged ahead of that.

Patches 1 and 2 are updates from a previous series I submitted a while back [1].
I have addressed Jacopo's feedback comments and moved them into this series.

Patch 3 adds HDR algorithm support to the RPi IPA and updates the VC4 tuning
files with the AGC channel config for HDR.

Patches 4 and 5 are minor changes needed in preparation for the Pi 5 pipeline
handler and IPA.

Thanks, Naush
