Isn't that a job for musb/gadget? Detecting D+/D- being shorted by
charger or something like that? I don't think BCI is able to detect
charger.

it's part of the charger detection right ? and according to trm, it's on
the BCI (actually BCC) role to take care of that :-)

Hm you are probably talking about TWL5031, which has redesigned
charger block that is named BCC. TWL4030 charger is different, called
BCI and requires software charger detection from what I see in it's
TRM.

ok, might be that I got confused. Then it's ok the way it is. So we need
other means to detect the charger :-p
