Merge tag 'for-v6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply

Pull power supply and reset updates from Sebastian Reichel:
 "Power-supply core:
   - introduce power_supply_show_enum_with_available() helper
   - change usb_types from an array into a bitmask
   - fix early usage of power_supply_property_is_writeable() resulting
     in sysfs files not being writable
   - fix missing temp1_max_alarm attribute in power-supply's hwmon
     devices

  Drivers:
   - max1720x: expose nvmem device
   - brcmstb: cleanup driver to use latest APIs
   - max77693: expose input and charging current limit
   - max17042_battery: fix state of charge reading for devices without
     current sensing
   - axp20x_battery: add AXP717 support
   - axp20x_battery: fix min/max voltage properties
   - axp20x_usb_power: add AXP717 support
   - axp20x_usb_power: add DT based input current limit

  Documentation updates

-		Represents the type of charging currently being applied to the

-		charging speeds. "Adaptive" means that the charger uses some
-		algorithm to adjust the charge rate dynamically, without
-		any user configuration required. "Custom" means that the charger
-		uses the charge_control_* properties as configuration for some
-		different algorithm. "Long Life" means the charger reduces its

-		means the charger bypasses the charging path around the
-		integrated converter allowing for a "smart" wall adaptor to
-		perform the power conversion externally.
+		Select the charging algorithm to use for a battery.
+
+		Standard:
+			Fully charge the battery at a moderate rate.
+		Fast:
+			Quickly charge the battery using fast-charge
+			technology. This is typically harder on the battery
+			than standard charging and may lower its lifespan.
+		Trickle:
+			Users who primarily operate the system while
+			plugged into an external power source can extend
+			battery life with this mode. Vendor tooling may
+			call this "Primarily AC Use".
+		Adaptive:
+			Automatically optimize battery charge rate based
+			on typical usage pattern.
+		Custom:
+			Use the charge_control_* properties to determine
+			when to start and stop charging. Advanced users
+			can use this to drastically extend battery life.
