Merge tag 'arc-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc
Pull ARC updates from Vineet Gupta:
"We have a relatively big changeset for ARC for 4.7.
The highlight is support for EZChip (now Mellanox) NPS-400 network
processor, a 400-Gb throughput C-programmable packet processor based
on ARC700 cores from Synopsys. See
http://www.mellanox.com/related-docs/prod_npu/PB_NPS-400.pdf
Also present are irqchip and clocksource drivers for NPS as agreed
with respective maintainers to go via ARC tree due to an soc header
dependency. I have the needed ACKs from Jason, Marc, Daniel. You
might run into a trivial merge conflict in drivers/irqchip/*
This EZChip platform support required some deep changes in ARC
architecture code and also opportunity to cleanup past sins (legacy
irq domains, missing irq domain lookup, hard coded timer irqs...)
Summary:
- Support for EZChip (now Mellanox) NPS-400 Network processor based
on ARC700
- NPS interrupt controller and clocksource drivers
- ARC timers probed off DT
- ARC iqrchips switching to linear domain (upgrade from legacy
domains)"

on wfe to safeguard against any programming errors in case an expected
