arm-soc: driver specific updates
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.
Merge branch 'next/devel-samsung-iommu' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/drivers
* 'next/devel-samsung-iommu' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
iommu/exynos: Add iommu driver for EXYNOS Platforms
