Subject: [REGRESSION] rtc: imx-sc: remove .read_alarm
Date: Wed, 8 Feb 2023 15:06:28 +0000	[thread overview]
Message-ID: <bbe470eaeeb17624444b37dbe35b0883193e475b.camel@toradex.com> (raw)

Hi Alexandre

Were you aware that this breaks the sysfs use case? E.g. before we were able to suspend and resume 10 seconds
later as follows:

echo +10 > /sys/class/rtc/rtc1/wakealarm; echo mem > /sys/power/state

Since the removal of .read_alarm in commit 7942121b8ca0 ("rtc: imx-sc: remove .read_alarm") this no longer
seems to work.

This seems like a regression or is this not supposed to work?

Thanks for clarifying.

Cheers

Marcel
