Subject: [git pull] IOMMU Updates for Linux v5.15
Hi Linus,
The tree is a bit more messy this time, mostly because there are many
IOMMU core changes included and driver patches which depend on them
living in different branches. So some cross-merging between branches was
necessary. With that said:
The following changes since commit 7c60610d476766e128cc4284bb6349732cbd6606:
Linux 5.14-rc6 (2021-08-15 13:40:53 -1000)
are available in the Git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git tags/iommu-updates-v5.15

Merge branches 'apple/dart', 'arm/smmu', 'iommu/fixes', 'x86/amd', 'x86/vt-d' and 'core' into next (2021-08-20 17:14:35 +0200)
----------------------------------------------------------------
IOMMU Updates for Linux v5.15
Including:
- New DART IOMMU driver for Apple Silicon M1 chips.
- Optimizations for iommu_[map/unmap] performance
- Selective TLB flush support for the AMD IOMMU driver to make
it more efficient on emulated IOMMUs.
- Rework IOVA setup and default domain type setting to move more
code out of IOMMU drivers and to support runtime switching
between certain types of default domains.
- VT-d Updates from Lu Baolu:
- Update the virtual command related registers
- Enable Intel IOMMU scalable mode by default
- Preset A/D bits for user space DMA usage
- Allow devices to have more than 32 outstanding PRs
- Various cleanups
- ARM SMMU Updates from Will Deacon:
- SMMUv3: Minor optimisation to avoid zeroing struct members on CMD submission
- SMMUv3: Increased use of batched commands to reduce submission latency
- SMMUv3: Refactoring in preparation for ECMDQ support
- SMMUv2: Fix races when probing devices with identical StreamIDs
- SMMUv2: Optimise walk cache flushing for Qualcomm implementations
- SMMUv2: Allow deep sleep states for some Qualcomm SoCs with shared clocks
- Various smaller optimizations, cleanups, and fixes
