    Linus Torvalds authored
    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)"
