Merge tag 'for-v6.8-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply
Pull power supply and reset updates from Sebastian Reichel:
"New features:
- bq24190: Add support for BQ24296 charger
Cleanups:
- all reset drivers: Stop using module_platform_driver_probe()
- gpio-restart: use devm_register_sys_off_handler
- pwr-mlxbf: support graceful reboot
- cw2015: correct time_to_empty units
- qcom-battmgr: Fix driver initialization sequence
- bq27xxx: Start/Stop delayed work in suspend/resume
- minor cleanups and fixes"
