Pull power supply and reset updates from Sebastian Reichel: "Power-supply core: - introduce power supply extensions, which allows adding properties to a power supply device from a separate driver. This will be used initially to extend the generic ACPI charger/battery driver with vendor extensions for charge thresholds. - convert all drivers from power_supply_for_each_device to new power_supply_for_each_psy(), which avoids lots of casting being done in the drivers. - avoid LED trigger like values in uevent for POWER_SUPPLY_PROP_CHARGE_BEHAVIOUR - introduce POWER_SUPPLY_PROP_CHARGE_TYPES, which is similar to the POWER_SUPPLY_PROP_CHARGE_TYPE property, but also lists the available options on the specific platform Power-supply drivers - dell-laptop: use new power_supply_charge_types_show/_parse helpers - stc3117: new driver for equally named fuel gauge chip - bq24190: add support for new POWER_SUPPLY_PROP_CHARGE_TYPES - bq24190: add BQ24297 support - bq27xxx: add voltage min design for bq27000/bq27200 - cros_charge-control: convert to new power supply extension API - multiple drivers: constify 'struct bin_attribute' - ds2782: convert to device managed resources - max1720x: add charge full property - max1720x: support extra thermistor temperatures - max17042: add max77705 support - ip5xxx-power: add support for IP5306 - ltc4162-l-charger: add ltc4162-f/s and ltc4015 support - gpio-charger: support for default charge current limit - misc small cleanups and fixes Reset drivers: - at91-poweroff: add sam9x7 support" * tag 'for-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply: (77 commits) power: supply: max1720x: add support for reading internal and thermistor temperatures power: supply: ltc4162l: Use GENMASK macro in bitmask operation power: supply: max17042: add max77705 fuel gauge support dt-bindings: power: supply: max17042: add max77705 support power: supply: add undervoltage health status property power: supply: max17042: add platform driver variant power: supply: max17042: make interrupt shared power: reset: keystone: Use syscon_regmap_lookup_by_phandle_args power: supply: Use str_enable_disable-like helpers platform/x86: dell-laptop: Use power_supply_charge_types_show/_parse() helpers power: supply: bq2415x_charger: Immediately reschedule delayed work on notifier events power: supply: Add STC3117 fuel gauge unit driver dt-bindings: power: supply: Add STC3117 Fuel Gauge power: supply: ug3105_battery: Let the core handle POWER_SUPPLY_PROP_TECHNOLOGY power: supply: gpio-charger: add support for default charge current limit dt-bindings: power: supply: gpio-charger: add support for default charge current limit power: supply: Use power_supply_external_power_changed() in __power_supply_changed_work() power: supply: core: fix build of extension sysfs group if CONFIG_SYSFS=n power: supply: bq2415x_charger: report charging state changes to userspace bq27xxx: add voltage min design for bq27000 and bq27200 ...

+  The STC3117 includes the STMicroelectronics OptimGauge algorithm.
+  It provides accurate battery state-of-charge (SOC) monitoring, tracks
+  battery parameter changes with operation conditions, temperature,
+  and aging, and allows the application to get a battery state-of-health
+  (SOH) indication.
+
+  An alarm output signals low SOC or low voltage conditions and also
+  indicates fault conditions like a missing or swapped battery.
