Datasheets for this chip, or the other (6332) are not public ... and I have no
access to any: whatever you see here is done with an accurate reading of downstream
drivers and a lot of debugging and research.

Anyway, MT6331 is a PMIC, MT6332 is also a PMIC (in this case, a companion pmic).

More is voltage regulators, display backlight PWM, LED PWM, some GPIOs, battery
charging, fuel gauge... and I think nothing else.

Anyway, okay I will list things out in the commit description.

Will do!
