Merge tag 'iommu-updates-v6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/iommu/linux 

Pull iommu updates from Joerg Roedel:
 "Core iommufd dependencies from Jason:
   - Change the iommufd fault handle into an always present hwpt handle
     in the domain
   - Give iommufd its own SW_MSI implementation along with some IRQ
     layer rework
   - Improvements to the handle attach API

  Core fixes for probe-issues from Robin

  Intel VT-d changes:
   - Checking for SVA support in domain allocation and attach paths
   - Move PCI ATS and PRI configuration into probe paths
   - Fix a pentential hang on reboot -f
   - Miscellaneous cleanups

  AMD-Vi changes:
   - Support for up to 2k IRQs per PCI device function
   - Set of smaller fixes

  ARM-SMMU changes:
   - SMMUv2 devicetree binding updates for Qualcomm implementations
     (QCS8300 GPU and MSM8937)
   - Clean up SMMUv2 runtime PM implementation to help with wider rework
     of pm_runtime_put_autosuspend()

  Rockchip driver changes:
   - Driver adjustments for recent DT probing changes

  S390 IOMMU changes:
   - Support for IOMMU passthrough

  Apple Dart changes:
   - Driver adjustments to meet ISP device requirements
   - Null-ptr deref fix
   - Disable subpage protection for DART 1"
