Pull timers and timekeeping updates from Thomas Gleixner:
"Core:
- Robustness improvements for the NOHZ tick management
- Fixes and consolidation of the NTP/RTC synchronization code
- Small fixes and improvements in various places
- A set of function documentation udpates and fixes
Drivers:
- Cleanups and improvements in various clocksoure/event drivers
- Removal of the EZChip NPS clocksource driver as the platfrom
support was removed from ARC
- The usual set of new device tree binding and json conversions
- The RTC driver which have been acked by the RTC maintainer:
* fix a long standing bug in the MC146818 library code which can
cause reading garbage during the RTC internal update.
* changes related to the NTP/RTC consolidation work"
