From 7c94caca877b0feeca6f5f7b07d48c508e20d58f Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Thu, 23 Jan 2020 21:58:47 -0800 Subject: [PATCH] alarmtimer: Use wakeup source from alarmtimer platform device Use the wakeup source that can be associated with the 'alarmtimer' platform device instead of registering another one by hand.
