Currently, the syscon-poweroff driver cleans the alarm enable bit during power
off. This behaviour makes it impossible to wake up the device using the RTC.
The first patch adds a mask option to the syscon-poweroff driver. It uses the
method suggested by Sebastian Reichel [0] to maintain compatibility with the
old binding.
The second patch update the device trees for the snvs component users.
Although I believe this should work on all the modified devices, I had only
imx6ul to test with.
Making the wake-up alarm work may require applying another patch [1], already
accepted to the rtc-snvs driver.
Thanks,
Guy.
