and it is due to an erroneous mask operation when reading back the alarm from
the RTC register.
This following patch should fix it:

i already forwarded it to our Marvell contact, waiting for feedback on
it.
Unfortunately, even with this patch, i cannot successfully make Casper
to resume, so more work is needed in this area.
