Merge tag 'for-v3.20' of git://git.infradead.org/battery-2.6

Pull power supply and reset changes from Sebastian Reichel:
 "New drivers:
   - charger driver for Maxim 77693
   - battery gauge driver for LTC 2941/2943
   - battery gauge driver for RT5033
   - reset driver for R-Mobile platforms

  Convert drivers to restart handler framework:
   - arm-versatile
   - at91
   - st-poweroff

  Misc:
   - remove deprecated sun6i reboot driver
   - use alarmtimer instead of rtc in charger-manager
   - misc fixes"
