I want to convert the axp20x PMIC poweroff handler to use the sys-off API, so it can be used as a fallback for if the SBI poweroff handler is unavailable. But the SBI poweroff handler still uses pm_power_off, so done alone, this would cause the axp20x callback to be called first, before the SBI poweroff handler has a chance to run.
In order to prevent this change in behavior, the SBI poweroff handler needs to be converted to the sys-off API first, at a higher priority.
This series performs the conversion, after accounting for the fact that the SBI poweroff handler is registered quite early during boot.
The first patch is a dependency for both this series and the PSCI series[1], so I would like to get at least patch 1 merged soon.
