[libcamera-devel] Pinephone 1.2 and libcamera

Mon Jun 27 08:46:02 CEST 2022

That is wonderful. Thanks for pointing me the OV5640 patches. And before 
I start back-porting these patches to my 5.15 branch, is there any git 
repo I can clone just to give a first try (with these modifications 
already inside)?
