Merge tag 'iommu-updates-v4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel:
"These changes include:
- support for the ACPI IORT table on ARM systems and patches to make
the ARM-SMMU driver make use of it
- conversion of the Exynos IOMMU driver to device dependency links
and implementation of runtime pm support based on that conversion
- update the Mediatek IOMMU driver to use the new struct
device->iommu_fwspec member
- implementation of dma_map/unmap_resource in the generic ARM
dma-iommu layer
- a number of smaller fixes and improvements all over the place"
