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"
