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

Pull arm-soc driver specific updates from Olof Johansson:
 "These changes are specific to some driver that may be used by multiple
  boards or socs.  The most significant change in here is the move of
  the samsung iommu code from a platform specific in-kernel interface to
  the generic iommu subsystem."

Fix up trivial conflicts in arch/arm/mach-exynos/Kconfig
