Merge tag 'for-v5.17' 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 "No Battery" health status

   - use library interpolation

   - add power_supply_battery_info documentation

   - migrate power_supply_battery_info to be fully heap allocated making
     it more obvious that it needs to be free'd manually

  Drivers:

   - max77976-charger: new driver

   - qcom-smbb: add pm8226 charger support

   - bq25890-charger: support battery temperature readings

   - ab8500: continue migrating towards using standard core APIs"

-Driver a GPIO line that can be used to turn the power off.
-
-The driver supports both level triggered and edge triggered power off.
-At driver load time, the driver will request the given gpio line and
-install a handler to power off the system. If the optional properties
-'input' is not found, the GPIO line will be driven in the inactive
-state. Otherwise its configured as an input.
-
-When the power-off handler is called, the gpio is configured as an
-output, and drive active, so triggering a level triggered power off
-condition. This will also cause an inactive->active edge condition, so
-triggering positive edge triggered power off. After a delay of 100ms,
-the GPIO is set to inactive, thus causing an active->inactive edge,
-triggering negative edge triggered power off. After another 100ms
-delay the GPIO is driver active again. If the power is still on and
-the CPU still running after a 3000ms delay, a WARN_ON(1) is emitted.
-
-Required properties:
-- compatible : should be "gpio-poweroff".
-- gpios : The GPIO to set high/low, see "gpios property" in
-  Documentation/devicetree/bindings/gpio/gpio.txt. If the pin should be
-  low to power down the board set it to "Active Low", otherwise set
-  gpio to "Active High".
-
-Optional properties:
-- input : Initially configure the GPIO line as an input. Only reconfigure
-  it to an output when the power-off handler is called. If this optional
-  property is not specified, the GPIO is initialized as an output in its
-  inactive state.
-- active-delay-ms: Delay (default 100) to wait after driving gpio active
-- inactive-delay-ms: Delay (default 100) to wait after driving gpio inactive
-- timeout-ms: Time to wait before asserting a WARN_ON(1). If nothing is
-              specified, 3000 ms is used.
-
-Examples:
-
-gpio-poweroff {
-	compatible = "gpio-poweroff";
-	gpios = <&gpio 4 0>;
-	timeout-ms = <3000>;
-};

+  System power off support via a GPIO line. When a shutdown is
+  executed the operating system is expected to switch the GPIO
+  from inactive to active. After a delay (active-delay-ms) it
+  is expected to be switched back to inactive. After another
+  delay (inactive-delay-ms) it is configured as active again.
+  Finally the operating system assumes the power off failed if
+  the system is still running after waiting some time (timeout-ms).
