Merge tag 'rtc-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "A lot of unnecessary code removal in here that ends up decreasing the
  number of lines in the subsystem. The ds1343 and ds1347 drivers got
  cleaned up. The rest are the usual fixes and new features.

  Subsystem:
   - fix warnings and errors with make W=1
   - UIE are now disabled while setting the RTC time
   - UIE are now disallowed when the RTC time is not set.

  Drivers:
   - remove unecessary .remove callbacks
   - Set RTC range for cros-ec, ds1343, ds1347, m41t80, s35390a, vt8500
   - Use devm_platform_ioremap_resource where applicable
   - rv3028: add clock out support"
