Merge tag 'arc-4.10-rc1-part1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc
Pull ARC updates from Vineet Gupta:
 "These are mostly timer/clocksource driver updates which were
  Reviewed/Acked by Daniel but had to be merged via ARC tree due to
  dependencies.

  I will follow up with another pull request with actual ARC changes
  early next week !

  Summary:

   - Moving ARC timer driver into drivers/clocksource

   - EZChip timer driver updates [Noam]

   - ARC AXS103 and HAPS platform updates [Alexey]"

* tag 'arc-4.10-rc1-part1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc:
  ARC: axs10x: really enable ARC PGU
  ARC: rename Zebu platform support to HAPS
  clocksource: nps: avoid maybe-uninitialized warning
  clocksource: Add clockevent support to NPS400 driver
  clocksource: update "fn" at CLOCKSOURCE_OF_DECLARE() of nps400 timer
  soc: Support for NPS HW scheduling
  clocksource: import ARC timer driver
  ARC: breakout timer include code into separate header ...
  ARC: move mcip.h into include/soc and adjust the includes
  ARC: breakout aux handling into a separate header
  ARC: time: move time_init() out of the driver
  ARC: timer: gfrc, rtc: build under same option (64-bit timers)
  ARC: timer: gfrc, rtc: Read BCR to detect whether hardware exists ...
  ARC: timer: gfrc, rtc: deuglify big endian code
