Merge tag 'soc-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC specific changes from Arnd Bergmann:
"Lots of changes specific to one of the SoC families. Some that stick
out are:
- mach-qcom gains new features, most importantly SMP support for the
newer chips (Stephen Boyd, Rohit Vaswani)
- mvebu gains support for three new SoCs: Armada 375, 380 and 385
(Thomas Petazzoni and Free-electrons team)
- SMP support for Rockchips (Heiko Stübner)
- Lots of i.MX changes (Shawn Guo)
- Added support for BCM5301x SoC (Hauke Mehrtens)
- Multiplatform support for Marvell Kirkwood and Dove (Andrew Lunn
and Sebastian Hesselbarth doing the final part of a long journey)
- Unify davinci platforms and remove obsolete ones (Sekhar Nori, Arnd
Bergmann)"
