Those patches are posted as one patchset mainly to demonstrate how to get
everything to work together. I also posted this as a single patch series
to get some feedback from other iommu developers, especially all those
involved in the generic iommu dt bindings.

For merging, I will split them into smaller series and try to get
respective acks.
