Pull RTC updates from Alexandre Belloni:
"It is now possible to add custom sysfs attributes while avoiding a
possible race condition. Unused code has been removed resulting in a
nice reduction of the code base. And more drivers have been switched
to SPDX by their maintainers.

Summary:

Subsystem:
- new helpers to add custom sysfs attributes
- struct rtc_task removal along with rtc_irq_[un]register()
- rtc_irq_set_state and rtc_irq_set_freq are not exported anymore

Drivers:
- armada38x: reset after rtc power loss
- ds1307: now supports m41t11
- isl1208: now supports isl1219 and tamper detection
- pcf2127: internal SRAM support"

Pull RTC updates from Alexandre Belloni:
"This contains a few series that have been in preparation for a while
and that will help systems with RTCs that will fail in 2038, 2069 or
2100.

Subsystem:
- Add tracepoints
- Rework of the RTC/nvmem API to allow drivers to discard struct
nvmem_config after registration
- New range API, drivers can now expose the useful range of the RTC
- New offset API the core is now able to add an offset to the RTC
time, modifying the supported range.
- Multiple rtc_time64_to_tm fixes
- Handle time_t overflow on 32 bit platforms in the core instead of
letting drivers do crazy things.
- remove rtc_control API

New driver:
- Intersil ISL12026

Drivers:
- Drivers exposing the RTC non volatile memory have been converted to
use nvmem
- Removed useless time and date validation
- Removed an indirection pattern that was a cargo cult from ancient
drivers
- Removed VLA usage
- Fixed a possible race condition in probe functions
- AB8540 support is dropped from ab8500
- pcf85363 now has alarm support"
