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. Best regards -- Marek Szyprowski, PhD Samsung R&D Institute Poland
