Merge tag 'drivers-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc into next

Pull ARM SoC driver changes from Olof Johansson:
 "SoC-near driver changes that we're merging through our tree.  Mostly
  because they depend on other changes we have staged, but in some cases
  because the driver maintainers preferred that we did it this way.

  This contains a largeish cleanup series of the omap_l3_noc bus driver,
  cpuidle rework for Exynos, some reset driver conversions and a long
  branch of TI EDMA fixes and cleanups, with more to come next release.

  The TI EDMA cleanups is a shared branch with the dmaengine tree, with
  a handful of Davinci-specific fixes on top.

  After discussion at last year's KS (and some more on the mailing
  lists), we are here adding a drivers/soc directory.  The purpose of
  this is to keep per-vendor shared code that's needed by different
  drivers but that doesn't fit into the MFD (nor drivers/platform)
  model.  We expect to keep merging contents for this hierarchy through
  arm-soc so we can keep an eye on what the vendors keep adding here and
  not making it a free-for-all to shove in crazy stuff"
