[libcamera-devel] [PATCH 0/8] ipa: rkisp1: Add autofocus algorithm

[Daniel Semkowicz]

Hi Jacopo,

Thank you for the information about the state. I see there is a lot of
traffic on libcamera mailing list, so I thought you probably have a
lot of work :)

In the mean time I tested my changes on different platform and found one
issue that needs an improvement, so I have two additional commits to
this series. Should I send them separately or resend this series as new
version with additional commits? There are no changes in already pushed
commits.

Best regards
Daniel
