Do you see a generic framework for pluggable algorithms on an abstracted
level, so that it could be used for the CC/CV charging, measurement and
temperature check algorithm that is found in e.g.
drivers/power/abx500_chargalg.c
drivers/power/ab8500_charger.c etc, or do you envision a set of pluggable
algorithms for this one hardware?

I'm asking because these drivers are a massive set of code and we may
need to start to abstract out and define library functions and frameworks
already now before it becomes impossible to contain.

Yours,
