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"
