Merge tag 'iommu-updates-v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel:
"Core changes:
- Constification of bus_type pointer
- Preparations for user-space page-fault delivery
- Use a named kmem_cache for IOVA magazines
Intel VT-d changes from Lu Baolu:
- Add RBTree to track iommu probed devices
- Add Intel IOMMU debugfs document
- Cleanup and refactoring
ARM-SMMU Updates from Will Deacon:
- Device-tree binding updates for a bunch of Qualcomm SoCs
- SMMUv2: Support for Qualcomm X1E80100 MDSS
- SMMUv3: Significant rework of the driver's STE manipulation and
domain handling code. This is the initial part of a larger scale
rework aiming to improve the driver's implementation of the
IOMMU-API in preparation for hooking up IOMMUFD support.
AMD-Vi Updates:
- Refactor GCR3 table support for SVA
- Cleanups
Some smaller cleanups and fixes"
