Merge tag 'iommu-updates-v4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/joro...

Pull IOMMU updates from Joerg Roedel:

 - support for interrupt virtualization in the AMD IOMMU driver. These
   patches were shared with the KVM tree and are already merged through
   that tree.

 - generic DT-binding support for the ARM-SMMU driver. With this the
   driver now makes use of the generic DMA-API code. This also required
   some changes outside of the IOMMU code, but these are acked by the
   respective maintainers.

 - more cleanups and fixes all over the place.
