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.
