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)"
