Merge tag 'for-v4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply

Pull power supply and reset changes from Sebastian Reichel:
 "New chip/feature support:
   - bq27xxx: support updating battery config from DT
   - bq24190: support loading battery charge info from DT
   - LTC2941: add LTC2942/LTC2944 support
   - max17042: add ACPI support
   - max1721x: new driver

  Misc:
   - Move bq27xxx w1 driver from w1 into power-supply subsystem
   - Introduce power_supply_set_input_current_limit_from_supplier
   - constify stuff
   - some minor fixes"
