Comment(by balajirrao):
Replying to [comment:49 andy]:
> lindi charger is quite complex state machine, in which it can do various
steps like wait or fast-charge and so on. If the charger is disabled, it
would turn all of it off and be certain it would never charge. When the
charger is enabled, it just gives it opportunity to charge depending on
its "program".

happen" to reach 3.84V but it will require great deal of discharge
pointlessly.

constant current charge mode (not good for battery for permanently
tethered device I guess), or set MBCC2 vmax (is it really this one that
sets Vth(res)? I didn't see it actually say it) in mach_gta02.c regulator
init stuff.
Yes, its MBCC2. Will set it to around (4.2 ~ 4.3) volts. Will be the first
thing I'll try tomorrow morning. Hopefully it'll work..
