Merge tag 'iommu-updates-v6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/iommu/linux

Pull iommu updates from Will Deacon:
 "Core:

   - Support for the "ats-supported" device-tree property

   - Removal of the 'ops' field from 'struct iommu_fwspec'

   - Introduction of iommu_paging_domain_alloc() and partial conversion
     of existing users

   - Introduce 'struct iommu_attach_handle' and provide corresponding
     IOMMU interfaces which will be used by the IOMMUFD subsystem

   - Remove stale documentation

   - Add missing MODULE_DESCRIPTION() macro

   - Misc cleanups

  Allwinner Sun50i:

   - Ensure bypass mode is disabled on H616 SoCs

   - Ensure page-tables are allocated below 4GiB for the 32-bit
     page-table walker

   - Add new device-tree compatible strings

  AMD Vi:

   - Use try_cmpxchg64() instead of cmpxchg64() when updating pte

  Arm SMMUv2:

   - Print much more useful information on context faults

   - Fix Qualcomm TBU probing when CONFIG_ARM_SMMU_QCOM_DEBUG=n

   - Add new Qualcomm device-tree bindings

  Arm SMMUv3:

   - Support for hardware update of access/dirty bits and reporting via
     IOMMUFD

   - More driver rework from Jason, this time updating the PASID/SVA
     support to prepare for full IOMMUFD support

   - Add missing MODULE_DESCRIPTION() macro

   - Minor fixes and cleanups

  NVIDIA Tegra:

   - Fix for benign fwspec initialisation issue exposed by rework on the
     core branch

  Intel VT-d:

   - Use try_cmpxchg64() instead of cmpxchg64() when updating pte

   - Use READ_ONCE() to read volatile descriptor status

   - Remove support for handling Execute-Requested requests

   - Avoid calling iommu_domain_alloc()

   - Minor fixes and refactoring

  Qualcomm MSM:

   - Updates to the device-tree bindings"
