Subject: [rtc-linux] [PATCH 0/2] imx: Fix power-up on RTC alarm
Date: Tue,  7 Feb 2017 14:54:12 +0200	[thread overview]
Message-ID: <1486472054-4367-1-git-send-email-guy.shapiro@mobi-wize.com> (raw)

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.
