Merge tag 'rtc-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux
Pull RTC updates from Alexandre Belloni:
"RTC for 4.9
Subsystem:
- delete owner assignment in multiple drivers
- constify rtc_class_ops structures
Drivers:
- ac100: support clock-output-names
- cmos: properly handle ACPI alarms and quirky BIOSes and other fixes
- ds1307: fix century bit support while staying comaptible with
previous behaviour by default
- ds1347: switch to regmap
- isl12057 is now handled by ds1307
- omap: support external wakeup
- rv8803: allow to disable voltage drop detection"
