Merge tag 'for-v4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply
Pull power supply and reset updates from Sebastian Reichel:
"New drivers:
- gemini-poweroff
- cpcap-charger (for Motorola Droid 4)
- battery-lego-ev3 (for LEGO Mindstorms EV3)
New chip/feature support:
- bq24190-charger: add runtime PM support
- bq24190-charger: add bq24192i support
- register masking for syscon-poweroff
... and misc small fixes & cleanups
