Hi,

This series addresses the long pending move of ARC timer code into
drivers/clocksource/.

Thx,
-Vineet

v3 -> v4

- dropped 2 patches.
  "rtc: implement read loop in "C" vs. inline asm" was a bug fix which is
  merged in upstream already
  "gfrc: boot print alongside other timers" squashed in final patch

- ARC_TIMERS_64BIT now have explicit dependency on ARC_TIMERS to fix the
  build issue when only 64BIT optin is selected		[Daniel]

- 0day build reported error with aux header movement patch - problem is in
  nps irqchip driver, which needs to be fixed before it can start using the
  new header

v2 -> v3

- Fixed a bunch of typos in changelogs				[Daniel]

- aux.h: stubs for {read,write}_aux_reg() inline functions(vs. macros)
  to cleanly avoid warnings in !ARC builds			[Daniel]

- Remove __maybe_used in driver given above			[Daniel]

- Ran checkpatch and fixed some space/tab issues

v1 -> v2

- Now 10 patches instead of 9 to handle BIG ENDIAN in arch agnostic way

- Moved fix for RTC (v1 2/9) ahead of queue (v2 1/10) to allow for easier
  stable backport

- Folded the Kconfig items for RTC and GFRC into single ARC_TIMERS_64BIT
  So no special casing for UP/SMP in Kconfig.
  Driver already handles the UP vs. SMP at runtime as needed

- convert WARN() to pr_warn()				[Daniel]
- Use of _BITUL() vs. constant 0x8000_0000		[Daniel]
- changelog spellos:					[Daniel]

Vineet Gupta (8):
  ARC: timer: gfrc, rtc: deuglify big endian code
  ARC: timer: gfrc, rtc: Read BCR to detect whether hardware exists ...
  ARC: time: move time_init() out of the driver
  ARC: timer: Build gfrc, rtc under same option (64-bit timers)
  ARC: breakout aux handling into a separate header
  ARC: move mcip.h into include/soc and adjust the includes
  ARC: breakout timer include code into separate header ...
  clocksource: import ARC timer driver
