Subject: [PATCH 0/2] rtc: ds1685: power-off fixes
Date: Tue, 13 Oct 2026 11:49:27 +0200 [thread overview]
Message-ID: <20261013094930.574-1-kaloz@kernel.org> (raw)
Two fixes for ds1685_rtc_poweroff(), on SGI O2 and Octane machines.
Patch 1 arms the wake-up alarm only if an alarm is set, so that stale
alarm registers no longer power the machine back on.
Patch 2 repeats the PAB write, clearing the kickstart and wake-up
flags with it, until power is removed.
Patch 1 was tested on an O2, patch 2 on an Octane.
Imre Kaloz (2):
rtc: ds1685: arm the wake-up alarm at power-off only if an alarm is
set
rtc: ds1685: keep setting PAB until power is removed
