Subject: [PATCH 0/2] firmware/psci: Switch to the sys-off handler API
Date: Sat,  5 Nov 2022 16:48:38 -0500	[thread overview]
Message-ID: <20221105214841.7828-1-samuel@sholland.org> (raw)

I am interested in converting the axp20x PMIC driver to use the sys-off
API for its poweroff handler, so it can be used as a fallback for the
SBI poweroff handler on RISC-V. But the PSCI poweroff handler still uses
pm_power_off, so done alone, this would cause the axp20x callback to be
called first, before the PSCI poweroff handler.

In order to prevent this change in behavior, the PSCI 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 PSCI poweroff handler is registered quite early during boot.

  kernel/reboot: Use the static sys-off handler for any priority
