Comment(by 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".
Balaji, yes it seems Vth(res) is too low. It's not that it would "never
happen" to reach 3.84V but it will require great deal of discharge
pointlessly.
We can either disable autostop so BATFULL just continues to be in 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.
