Merge tag 'iommu-updates-v7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/iommu/linux

Pull iommu updates from Joerg Roedel:
 "Core changes:
   - Rust bindings for IO-pgtable code
   - IOMMU page allocation debugging support
   - Disable ATS during PCI resets

  Intel VT-d changes:
   - Skip dev-iotlb flush for inaccessible PCIe device
   - Flush cache for PASID table before using it
   - Use right invalidation method for SVA and NESTED domains
   - Ensure atomicity in context and PASID entry updates

  AMD-Vi changes:
   - Support for nested translations
   - Other minor improvements

  ARM-SMMU-v2 changes:
   - Configure SoC-specific prefetcher settings for Qualcomm's "MDSS"

  ARM-SMMU-v3 changes:
   - Improve CMDQ locking fairness for pathetically small queue sizes
   - Remove tracking of the IAS as this is only relevant for AArch32 and
     was causing C_BAD_STE errors
   - Add device-tree support for NVIDIA's CMDQV extension
   - Allow some hitless transitions for the 'MEV' and 'EATS' STE fields
   - Don't disable ATS for nested S1-bypass nested domains
   - Additions to the kunit selftests"
