Merge tag 'rtc-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "Most of the changes are a rework of the cmos driver by Rafael and
  fixes for issues found using static checkers. The removal of a driver
  leads to a reduction of the number of LOC of the subsystem.

  Removed driver:
   - davinci

  Updates:
   - convert i2c drivers to .probe_new
   - fix spelling mistakes and duplicated words in comments
   - cmos: rework wake setup and ACPI event handling
   - cros-ec: Limit RTC alarm range to fix alarmtimer
   - ds1347: fix century register handling
   - efi: wakeup support
   - isl12022: temperature sensor support
   - pcf85063: fix read_alarm and clkout
   - pcf8523: use stop bit to detect invalid time
   - pcf8563: use RTC_FEATURE_ALARM
   - snvs: be more flexible on LPSRT reads
   - many static checker fixes"
