Merge tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform changes from Olof Johansson:
"New core SoC-specific changes.
New platforms:
* Introduction of a vendor, Hisilicon, and one of their SoCs with
some random numerical product name.
* Introduction of EFM32, embedded platform from Silicon Labs (ARMv7m,
i.e. !MMU).
* Marvell Berlin series of SoCs, which include the one in Chromecast.
* MOXA platform support, ARM9-based platform used mostly in
industrial products
* Support for Freescale's i.MX50 SoC.
Other work:
* Renesas work for new platforms and drivers, and conversion over to
more multiplatform-friendly device registration schemes.
* SMP support for Allwinner sunxi platforms.
* ... plus a bunch of other stuff across various platforms"
