Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform updates from Arnd Bergmann: "We get support for three new 32-bit SoC platforms this time. The amount of changes in arch/arm for any of them is miniscule, as all the interesting code is in device driver subsystems (irqchip, clk, pinctrl, ...) these days. I'm listing them here, as the addition of the Kconfig statement is the main relevant milestone for a new platform. In each case, some drivers are are shared with existing platforms, while other drivers are added for v4.7 as well, or come in a later release. - The Aspeed platform is probably the most interesting one, this is what most whitebox servers use as their baseboard management controller. We get support for the very common ast2400 and ast2500 SoCs. The OpenBMC project focuses on this chip, and the LWN article about their ELC 2016 presentation at https://lwn.net/Articles/683320/ triggered the submission, but the code comes from IBM's OpenPOWER team rather than the team at Facebook. There are still a lot more drivers that need to get added over time, and I hope both teams can work together on that. - OXNAS is an old platform for Network Attached Storage devices from Oxford Semiconductor. There are models with ARM10 (!) and ARM11MPCore cores, but for now, we only support the original ARM9 based versions. The product lineup was subsequently part of PLX, Avago and now the new Broadcom Ltd. https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas has some more information. - V2M-MPS2 is a prototyping platform from ARM for their Cortex-M cores and is related to the existing Realview / Versatile Express lineup, but without MMU. We now support various NOMMU platforms, so adding a new one is fairly straightforward. http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/ has detailed information about the platform. Other noteworthy updates: - Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain Lemieux are now maintaining the platform. This is an older ARM9 based platform from NXP (not Freescale), but it remains in use in embedded markets. - Kevin Hilman is now co-maintaining the Amlogic Meson platform for both 32-bit and 64-bit ARM, and started contributing some patches. - As is often the case, work on the OMAP platforms makes up the bulk of the actual SoC code changes in arch/arm, but there isn't a lot of that either" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (42 commits) MAINTAINERS: ARM/Amlogic: add co-maintainer, misc. updates MAINTAINERS: add ARM/NXP LPC32XX SoC specific drivers to the section MAINTAINERS: add new maintainers of NXP LPC32xx SoC MAINTAINERS: move ARM/NXP LPC32xx record to ARM section arm: Add Aspeed machine ARM: lpc32xx: remove duplicate const on lpc32xx_auxdata_lookup ARM: lpc32xx: remove leftovers of legacy clock source and provider drivers ARM: lpc32xx: remove reboot header file ARM: dove: Remove CLK_IS_ROOT ARM: orion5x: Remove CLK_IS_ROOT ARM: mv78xx0: Remove CLK_IS_ROOT ARM: davinci: da850: use clk->set_parent for async3 ARM: davinci: Move clock init after ioremap.
