Merge tag 'iommu-updates-v6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/iommu/linux

Pull iommu updates from Will Deacon:
"Core:
- Remove the 'pgsize_bitmap' member from 'struct iommu_ops'
- Convert the x86 drivers over to msi_create_parent_irq_domain()

AMD-Vi:
- Add support for examining driver/device internals via debugfs
- Add support for "HATDis" to disable host translation when it is not
supported
- Add support for limiting the maximum host translation level based
on EFR[HATS]

Apple DART:
- Don't enable as built-in by default when ARCH_APPLE is selected

Arm SMMU:
- Devicetree bindings update for the Qualcomm SMMU in the "Milos" SoC
- Support for Qualcomm SM6115 MDSS parts
- Disable PRR on Qualcomm SM8250 as using these bits causes the
hypervisor to explode

Intel VT-d:
- Reorganize Intel VT-d to be ready for iommupt
- Optimize iotlb_sync_map for non-caching/non-RWBF modes
- Fix missed PASID in dev TLB invalidation in cache_tag_flush_all()

Mediatek:
- Fix build warnings when W=1

Samsung Exynos:
- Add support for reserved memory regions specified by the bootloader

TI OMAP:
- Use syscon_regmap_lookup_by_phandle_args() instead of parsing the
node manually

Misc:
- Cleanups and minor fixes across the board"

iommu/amd: Wrap debugfs ABI testing symbols snippets in literal code blocks

Commit 39215bb3b0d929 ("iommu/amd: Add documentation for AMD IOMMU
debugfs support") documents debugfs ABI symbols for AMD IOMMU, but
forgets to wrap examples snippets and their output in literal code
blocks, hence Sphinx reports indentation warnings:

Documentation/ABI/testing/debugfs-amd-iommu:31: ERROR: Unexpected indentation. [docutils]
Documentation/ABI/testing/debugfs-amd-iommu:31: WARNING: Block quote ends without a blank line; unexpected unindent. [docutils]
Documentation/ABI/testing/debugfs-amd-iommu:31: WARNING: Block quote ends without a blank line; unexpected unindent. [docutils]

Wrap them to fix the warnings.
