Hi Linus,

Here is the pull-request for the RTC subsystem for 4.17.

It 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.

The following changes since commit 7928b2cbe55b2a410a0f5c1f154610059c57b1b2:

  Linux 4.16-rc1 (2018-02-11 15:04:29 -0800)

are available in the Git repository at:

  rtc: snvs: Fix usage of snvs_rtc_enable (2018-04-03 16:43:36 +0200)

----------------------------------------------------------------
RTC for 4.17

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
