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)" * tag 'arc-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc: (37 commits) arc: axs103_smp: Fix CPU frequency to 100MHz for dual-core arc: axs10x: Add DT bindings for I2S PLL Clock ARC: pae: STRICT_MM_TYPECHECKS was broken ARC: Add eznps platform to Kconfig and Makefile ARC: [plat-eznps] Use dedicated COMMAND_LINE_SIZE ARC: [plat-eznps] Use dedicated cpu_relax() ARC: [plat-eznps] Use dedicated identity auxiliary register.
