Subject: [PATCH 0/3] rtc: pcf2127: add alarm support
Date: Sun, 7 Jun 2020 13:06:07 -0400 [thread overview]
Message-ID: <20200607170610.24534-1-liambeguin@gmail.com> (raw)
From: Liam Beguin <lvb@xiphos.com>
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.
This was tested on a PCA2129, with:
$ date "2010-10-10 10:10"
Sun Oct 10 10:10:00 UTC 2010
$ /usr/sbin/rtcwake -u -d /dev/rtc0 -s10 --mode off
[ ... ]
$ # power on after 10 seconds
