Subject: [PATCH v1 0/4] add alarm support for the rtc-ab-eoz9
Date: Mon, 5 Apr 2021 10:13:30 -0400 [thread overview]
Message-ID: <20210405141334.3884528-1-liambeguin@gmail.com> (raw)
From: Liam Beguin <lvb@xiphos.com>
Add alarm support for the rtc-ab-eoz9.
The board used to test this series has the interrupt line of the RTC
connected to a circuit controlling the power of the board.
An event on the interrupt line while the board is off will power it on.
Because of these hardware limitations, the irq handler added in this
patch wasn't fully tested.
The alarm functionality was tested, with:
$ date "2010-10-10 10:10"
Sun Oct 10 10:10:00 UTC 2010
$ /usr/sbin/rtcwake -u -d /dev/rtc0 -s20 --mode off
[ ... ]
$ # power on after 20 seconds
