The battery monitor is a DS2760 or compatible device. I don't recall what the charger chip is, though it
probably doesn't matter much for your purposes.
As I mentioned the other day, I think that all you need to do is arrange for the battery management code in
the kernel to enable charging when USB is connected and AC is absent. This is probably just a case of
tweaking h5400_ac_power() in battery_h5400.c and arranging for h3600_ac_in_isr() to be called on USB in/out
events. It looks like h5400_set_charger() will already cope with selecting between the different power
sources.
