The patch titled
Subject: rtc: max77686: Allow the max77686 rtc to wakeup the system
has been removed from the -mm tree. Its filename was
rtc-max77686-allow-the-max77686-rtc-to-wakeup-the-system.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: rtc: max77686: Allow the max77686 rtc to wakeup the system
This series add support for the Real Time clock present in the Maxim 77802
Power Managment IC. The version number is quite high because it
previously was part of a bigger series [0] that aimed to add support for
all the devices in the max77802 PMIC. But now that the max77802
dependencies were already merged for 3.17, the series were split but I
kept the version numbering.
While working on the max77802 rtc support a lot of feedback was given and
the issues pointed out also apply to a driver for a similar PMIC RTC
(max77686). So patches 01/06 to 05/06 in the series are cleanups for the
max77686 driver and patch 06/06 adds the support for the max77802 RTC.
The series were tested on an Exynos5250 Snow (max77686) and
Exynos5420 Peach Pit (max77802) machines.
This patch (of 6):
The max77686 includes an RTC that keeps power during suspend. It's
convenient to be able to use it as a wakeup source.
