The bq25892 model relies on external charger-type detection and once that is done the bq25890_charger code will update the input current and if pumpexpress is used also the input voltage. In this case, when the initial power_supply_changed() call is made from the interrupt handler, the input settings are 5V/0.5A which on many devices is not enough power to charge (while the device is on). On many devices the fuel-gauge relies in its external_power_changed callback to timely signal userspace about charging <-> discharging status changes. Add a power_supply_changed() call after updating the input current or voltage. This allows the fuel-gauge driver to timely recheck if the battery is charging after the new input settings have been applied and then it can immediately notify userspace about this.
