Merge tag 'for-v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply
Pull power supply and reset updates from Sebastian Reichel:
"battery/charger driver changes:
- core:
- provide function stubs if CONFIG_POWER_SUPPLY=n
- reduce loglevel for probe defer info
- surface:
- new battery and charger drivers for Surface
- bq27xxx:
- add bq78z100 support
- fix current_now/power_avg for newer chips
- cw2015:
- add CHARGE_NOW support
- ab8500:
- drop pdata support
- convert most DT bindings to YAML
- lots of minor fixes and cleanups
reset drivers:
- ltc2952-poweroff:
- make trigger delay configurable from DT
- minor fixes and cleanups"
