Subject: [git pull] IOMMU Updates for Linux v6.14
Hi Linus,
The following changes since commit 5bc55a333a2f7316b58edc7573e8e893f7acb532:
Linux 6.13-rc7 (2025-01-12 14:37:56 -0800)
are available in the Git repository at:

----------------------------------------------------------------
IOMMU Updates for Linux v6.14
Including:
- 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.
