Merge tag 'iommu-updates-v4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
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. * tag 'iommu-updates-v4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (40 commits) iommu/amd: No need to wait iommu completion if no dte irq entry change iommu/amd: Free domain id when free a domain of struct dma_ops_domain iommu/amd: Use standard bitmap operation to set bitmap iommu/amd: Clean up the cmpxchg64 invocation iommu/io-pgtable-arm: Check for v7s-incapable systems iommu/dma: Avoid PCI host bridge windows iommu/dma: Add support for mapping MSIs iommu/arm-smmu: Set domain geometry iommu/arm-smmu: Wire up generic configuration support Docs: dt: document ARM SMMU generic binding usage iommu/arm-smmu: Convert to iommu_fwspec iommu/arm-smmu: Intelligent SMR allocation iommu/arm-smmu: Add a stream map entry iterator iommu/arm-smmu: Streamline SMMU data lookups iommu/arm-smmu: Refactor mmu-masters handling iommu/arm-smmu: Keep track of S2CR state iommu/arm-smmu: Consolidate stream map entry state iommu/arm-smmu: Handle stream IDs more dynamically iommu/arm-smmu: Set PRIVCFG in stage 1 STEs iommu/arm-smmu: Support non-PCI devices with SMMUv3 ...
