From: Noam Camus
Adding EZchip NPS400 support.
NPS internal interrupts are internally handled at
Multi Thread Manager (MTM) that is signaled for deactivating
an interrupt.
External interrupts is handled also at Global Interrupt
Controller (GIC) e.g. serial and network devices.

Add internal tick generator which is shared by all cores.
Each cluster of cores view it through dedicated address.
This is used for SMP system where all CPUs synced by same
clock source.

Change Log--
v2:
Add header file include/soc/nps/common.h.
Now to build we do not depend on ARC subtree.
General summay:
Both drivers are now apart of previous basic patch set of new platform for ARC.
The rest is now can be seen at ARC srctree:
https://git.kernel.org/cgit/linux/
From: Noam Camus
This header file is for NPS400 SoC.
It includes macros for accessing memory mapped registers.
These are functional registers that core can use to configure SoC.

From: Alexey Brodkin
UARTs usually have fixed clock so we're switching to use of
constant values instead of something derived from core clock
frequency.
Among other things this will allow us to get rid of
arc_{get|set}_core_freq() and switch to generic clock
framework later on.

ARC Timers so far have been handled as "legacy" w/o explicit description
in DT. This poses challenge for newer platforms wanting to use them.
This series will eventually help move timers over to DT.
This patch does a small change of using a CPU notifier to set clockevent
on non-
From: Alexey Brodkin
For AXS103, certain bitfile configurations may not work with stock
"clock-frequency" specified in DT. Instead of duplicating the DT files, we
fixup the DT in-place.
This used to be done differently - as in top level "clock-frequency" was
read very early from FDT and exported
- Remove explicit clocksource setup and let it be done by OF framework
by defining CLOCKSOURCE_OF_DECLARE() for various timers
- This allows multiple clocksources to be potentially registered
simultaneouly: previously we could only do one - as all of them had
same arc_counter_setup() routine
- timer frequency is derived from DT (no longer rely on top level
DT "clock-frequency" probed early and exported by asm/clk.h)
- TIMER0_IRQ need not be exported across arch code, confided to intc as
it is property of same

Hi,
This mini-series came out as a result of discussions during EZChip platform
code review.
This switches ARC timers to DT based probe and removes the homebrew clk API
we had before.
@Rob could you please take a look at the DT bindings.
@Daniel any comments would be appreciated !
Thx,
-Vineet
This allows us to introduce timers in DT in next commit
