[libcamera-devel] [PATCH v3 0/8] ipa: rkisp1: Add autofocus algorithm

[Daniel Semkowicz]

Hi!

This is a patch series with a common AF algorithm implementation
basing on the IPU3 AF version. The common part was then used to
implement AF for the rkisp1 ISP.

Early version of this serie was uploaded in the July, but there were
some change in the IPA in the meantime. The current version was updated
to the new IPA code and has most of the comments from the v2 review
fixed.

Best regards
Daniel Semkowicz
