Merge tag 'for-v5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply
Pull power supply and reset updates from Sebastian Reichel:
"Core:
- Add over-current health state
- Add standard, adaptive and custom charge types
- Add new properties for start/end charge threshold
New Drivers / Hardware:
- UCS1002 Programmable USB Port Power Controller
- Ingenic JZ47xx Battery Fuel Gauge
- AXP20x USB Power: Add AXP813 support
- AT91 poweroff: Add SAM9X60 support
- OLPC battery: Add XO-1.5 and XO-1.75 support
Misc Changes:
- syscon-reboot: support mask property
- AXP288 fuel gauge: Blacklist ACEPC T8/T11. Looks like some vendor
thought it's a good idea to build a desktop system with a fuel
gauge, that slowly "discharges"...
- cpcap-battery: Fix calculation errors
- misc fixes"
