Merge tag 'rtc-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "This cycle, we have a new RTC driver, for the SpacemiT P1. The optee
  driver gets alarm support. We also get a fix for a race condition that
  was fairly rare unless while stress testing the alarms.

  Subsystem:
   - Fix race when setting alarm
   - Ensure alarm irq is enabled when UIE is enabled
   - remove unneeded 'fast_io' parameter in regmap_config

  New driver:
   - SpacemiT P1 RTC

  Drivers:
   - efi: Remove wakeup functionality
   - optee: add alarms support
   - s3c: Drop support for S3C2410
   - zynqmp: Restore alarm functionality after kexec transition"
