Subject: [PATCH 0/2] power: supply: gpio-charger: add support for
 fast-charge timer

On some devices like TIs BQ24081 battery charger it is possible to activate
or deactivate a fast-charge timer that provides a backup safety for charge
termination. In case of the BQ24081 it is a fixed 7-hour timer. Add support
for enabling/disabling the fast-charge timer via GPIO.
