Merge tag 'iommu-updates-v5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel: - ARM-SMMU support for the TLB range invalidation command in SMMUv3.2 - ARM-SMMU introduction of command batching helpers to batch up CD and ATC invalidation - ARM-SMMU support for PCI PASID, along with necessary PCI symbol exports - Introduce a generic (actually rename an existing) IOMMU related pointer in struct device and reduce the IOMMU related pointers - Some fixes for the OMAP IOMMU driver to make it build on 64bit architectures - Various smaller fixes and improvements * tag 'iommu-updates-v5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (39 commits) iommu: Move fwspec->iommu_priv to struct dev_iommu iommu/virtio: Use accessor functions for iommu private data iommu/qcom: Use accessor functions for iommu private data iommu/mediatek: Use accessor functions for iommu private data iommu/renesas: Use accessor functions for iommu private data iommu/arm-smmu: Use accessor functions for iommu private data iommu/arm-smmu: Refactor master_cfg/fwspec usage iommu/arm-smmu-v3: Use accessor functions for iommu private data iommu: Introduce accessors for iommu private data iommu/arm-smmu: Fix uninitilized variable warning iommu: Move iommu_fwspec to struct dev_iommu iommu: Rename struct iommu_param to dev_iommu iommu/tegra-gart: Remove direct access of dev->iommu_fwspec drm/msm/mdp5: Remove direct access of dev->iommu_fwspec ACPI/IORT: Remove direct access of dev->iommu_fwspec iommu: Define dev_iommu_fwspec_get() for !CONFIG_IOMMU_API iommu/virtio: Reject IOMMU page granule larger than PAGE_SIZE iommu/virtio: Fix freeing of incomplete domains iommu/virtio: Fix sparse warning iommu/vt-d: Add build dependency on IOASID ...
