Subject: [PATCH v3 02/14] mfd: max77686: Allow the max77686 rtc to wakeup the system
Date: Thu, 19 Jun 2014 20:20:28 +0200 [thread overview]
Message-ID: <1403202040-12641-3-git-send-email-javier.martinez@collabora.co.uk> (raw)
In-Reply-To: <1403202040-12641-1-git-send-email-javier.martinez@collabora.co.uk>
From: Doug Anderson <dianders@chromium.org>
The max77686 includes an RTC that keeps power during suspend. It's
convenient to be able to use it as a wakeup source.
