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

Pull ARM driver updates from Olof Johansson:
 "Updates of SoC-near drivers and other driver updates that makes more
  sense to take through our tree.

  The largest part of this is a conversion of device registration for
  some renesas shmobile/sh devices over to use resources.  This has
  required coordination with the corresponding arch/sh changes, and
  we've agreed to merge the arch/sh changes through our tree.

  Added in this branch is support for Trusted Foundations secure
  firmware, which is what is used on many of the commercial Nvidia Tegra
  products that are in the market, including the Nvidia Shield.  The
  code is local to arch/arm at this time since it's uncertain whether it
  will be shared with arm64 longer-term, if needed we will refactor
  later.

  A couple of new RTC drivers used on ARM boards, merged through our
  tree on request by the RTC maintainer.

  ... plus a bunch of smaller updates across the board, gpio conversions
  for davinci, etc"
