[libcamera-devel] [PATCH] ipa: raspberrypi: Remove generic "pause" mechanism from Algorithm

Mon Nov 21 15:47:29 CET 2022
No existing Algorithm used the base pause(), resume() functions
or the paused_ flag, nor is there a need or a generic pause API.
Remove these. The AGC and AWB algorithms now have methods named
disableAuto(), enableAuto() which better describe their functionality.
