Merge tag 'iommu-updates-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/iommu/linux

Pull iommu updates from Joerg Roedel:
 "Core changes:
   - PASID support for the blocked_domain

  ARM-SMMU Updates:
   - SMMUv2:
      - Implement per-client prefetcher configuration on Qualcomm SoCs
      - Support for the Adreno SMMU on Qualcomm's SDM670 SOC
   - SMMUv3:
      - Pretty-printing of event records
      - Drop the ->domain_alloc_paging implementation in favour of
        domain_alloc_paging_flags(flags==0)
   - IO-PGTable:
      - Generalisation of the page-table walker to enable external
        walkers (e.g. for debugging unexpected page-faults from the GPU)
      - Minor fix for handling concatenated PGDs at stage-2 with 16KiB
        pages
   - Misc:
      - Clean-up device probing and replace the crufty probe-deferral
        hack with a more robust implementation of
        arm_smmu_get_by_fwnode()
      - Device-tree binding updates for a bunch of Qualcomm platforms

  Intel VT-d Updates:
   - Remove domain_alloc_paging()
   - Remove capability audit code
   - Draining PRQ in sva unbind path when FPD bit set
   - Link cache tags of same iommu unit together

  AMD-Vi Updates:
   - Use CMPXCHG128 to update DTE
   - Cleanups of the domain_alloc_paging() path

  RiscV IOMMU:
   - Platform MSI support
   - Shutdown support

  Rockchip IOMMU:
   - Add DT bindings for Rockchip RK3576

  More smaller fixes and cleanups"
