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
