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"
