Hello Linus,

Here is the RTC subsystem pull request for 6.6. The pcf2127 driver was
reworked heavily to add support for the pcf2131. This also introduces a
way for drivers to report the alarm range which is going to be used to
fix a related alarmtimer issue in the next release.

I extended the expiration date of my signing subkey so you will have to
update my key to be able to verify the tag signature.

The following changes since commit 06c2afb862f9da8dc5efa4b6076a0e48c3fbaaa5:

----------------------------------------------------------------
RTC for 6.6

Subsystem:
- Add a way for drivers to tell the core the supported alarm range is smaller
than the date range. This is not used yet but will be useful for the
alarmtimers in the next release.
- fix Wvoid-pointer-to-enum-cast warnings
- remove redundant of_match_ptr()
- stop warning for invalid alarms when the alarm is disabled

Drivers:
- isl12022: allow setting the trip level for battery level detection
- pcf2127: add support for PCF2131 and multiple timestamps
- stm32: time precision improvement, many fixes
- twl: NVRAM support
