[libcamera-devel] [PATCH v1 4/7] ipa: ipu3: use process method for all algorithms

[Jean-Michel Hautbois]

The main goal will be to have the same process() prototype for all
algorithms, each of them would then grab the values needed using a
metadata exchange way (for instance, current analogue gain, shutter time,
or red/blue gains calculated in the AWB algorithm from AGC, etc.).
