Hi,
It seems that bq27xxx_battery_update does not call power_supply_changed when the charging status changes, and instead only when the capacity changes.
This can cause considerable delays in reporting charging status changes to userspace. This patch turns the battery status reading function into one that returns the value directly (as other *_read functions), adds the status to the cache, uses the cache when reporting the values and finally will trigger power_supply_changed when the charging status changes.
There is still a noticable delay in detecting charger status, but that seems to have a different cause.
Cheers, Merlijn
