Merge tag 'iommu-updates-v4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel:
"Slightly more changes than usual this time:
- KDump Kernel IOMMU take-over code for AMD IOMMU. The code now tries
to preserve the mappings of the kernel so that master aborts for
devices are avoided. Master aborts cause some devices to fail in
the kdump kernel, so this code makes the dump more likely to
succeed when AMD IOMMU is enabled.
- common flush queue implementation for IOVA code users. The code is
still optional, but AMD and Intel IOMMU drivers had their own
implementation which is now unified.
- finish support for iommu-groups. All drivers implement this feature
now so that IOMMU core code can rely on it.
- finish support for 'struct iommu_device' in iommu drivers. All
drivers now use the interface.
- new functions in the IOMMU-API for explicit IO/TLB flushing. This
will help to reduce the number of IO/TLB flushes when IOMMU drivers
support this interface.
- support for mt2712 in the Mediatek IOMMU driver
- new IOMMU driver for QCOM hardware
- system PM support for ARM-SMMU
- shutdown method for ARM-SMMU-v3
- some constification patches
- various other small improvements and fixes"
