Merge tag 'rtc-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "Many cleanups and a few drivers removal this cycle.

  Subsystem:
   - Introduce features bitfield and the first feature: RTC_FEATURE_ALARM

  Removed drivers:
   - ab3100
   - coh901331
   - tx4939
   - sirfsoc

  Drivers:
   - use rtc_lock and rtc_unlock instead of opencoding
   - constify all struct rtc_class_ops
   - quiet maybe-unused variable warning
   - replace spin_lock_irqsave with spin_lock in hard IRQ
   - pcf2127: disable Power-On Reset Override and run OTP refresh"
