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)"
