[libcamera-devel] [PATCH v4 0/7] Raspberry Pi AGC digital gain fixes

[Naushir Patuck]

Hi,

Version 4 of this series only has one change from the previous versions:

In patch 6/7, the IPA cookie (index into the RPiMetadata array) is passed from
the pipeline handler into the IPA rather than the other way around.  This helps
simplify some of our future work on per-frame-control.

There is still lots of discussion on this series to be had, particularly for
patch 1/7 where we add a cookie to DelayedControls, so feel free to provide some
feedback.

Regards,
Naush
