Pull power supply and reset updates from Sebastian Reichel:
 "Power-supply core:

   - introduce power supply extensions, which allows adding properties
     to a power supply device from a separate driver. This will be used
     initially to extend the generic ACPI charger/battery driver with
     vendor extensions for charge thresholds.

   - convert all drivers from power_supply_for_each_device to new
     power_supply_for_each_psy(), which avoids lots of casting being
     done in the drivers.

   - avoid LED trigger like values in uevent for
     POWER_SUPPLY_PROP_CHARGE_BEHAVIOUR

   - introduce POWER_SUPPLY_PROP_CHARGE_TYPES, which is similar to the
     POWER_SUPPLY_PROP_CHARGE_TYPE property, but also lists the
     available options on the specific platform

  Power-supply drivers

   - dell-laptop: use new power_supply_charge_types_show/_parse helpers

   - stc3117: new driver for equally named fuel gauge chip

   - bq24190: add support for new POWER_SUPPLY_PROP_CHARGE_TYPES

   - bq24190: add BQ24297 support

   - bq27xxx: add voltage min design for bq27000/bq27200

   - cros_charge-control: convert to new power supply extension API

   - multiple drivers: constify 'struct bin_attribute'

   - ds2782: convert to device managed resources

   - max1720x: add charge full property

   - max1720x: support extra thermistor temperatures

   - max17042: add max77705 support

   - ip5xxx-power: add support for IP5306

   - ltc4162-l-charger: add ltc4162-f/s and ltc4015 support

   - gpio-charger: support for default charge current limit

   - misc small cleanups and fixes

  Reset drivers:

   - at91-poweroff: add sam9x7 support"
