This driver implements poweroff/reboot support for the SpacemiT P1 PMIC
chip, which is commonly paired with the SpacemiT K1 SoC.

The SpacemiT P1 support is implemented as a MFD driver, so the access is
done directly through the regmap interface. Reboot or poweroff is
triggered by setting a specific bit in a control register, which is
automatically cleared by the hardware afterwards.

This driver implements poweroff/reboot support for T-Head TH1520 SoCs
running the AON firmware by sending a message to the AON firmware's WDG
part.

This is a auxiliary device driver, and expects the AON channel to be
passed via the platform_data of the auxiliary device.

Pull power supply and reset updates from Sebastian Reichel:
 "Power-supply core:
   - battery-info: replace any DT specific bits with fwnode usage
   - replace any device-tree code with generic fwnode based handling

  Power-supply drivers:
   - ug3105_battery: use battery-info API
   - qcom_battmgr: report capacity
   - qcom_battmgr: support LiPo battery reporting
   - add missing missing power-supply ref to a bunch of DT bindings
   - update drivers regarding pm_runtime_autosuspend() usage
   - misc minor fixes and cleanups

  Reset drivers:
   - misc minor cleanups"

The Toradex Embedded Controller is currently only present on Toradex
SMARC iMX8MP and iMX95 SoMs.  Hence add a dependency on ARCH_MXC, to
prevent asking the user about this driver when configuring a kernel
without NXP i.MX SoC family support.

Toradex SMARC iMX8MP and SMARC iMX95 SoM modules use a small Embedded
Controller (EC) to manage power and reset functions and related SMARC
signals.

This driver implements power-off and reboot handlers, communicating with
the EC via I2C to issue the appropriate power management commands.

During probe, the driver logs the Embedded Controller ID (unique ID for
each SMARC board supported) in hex format along with the firmware version.
