Merge tag 'iommu-updates-v4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel:
- big-endian support and preparation for defered probing for the Exynos
IOMMU driver
- simplifications in iommu-group id handling
- support for Mediatek generation one IOMMU hardware
- conversion of the AMD IOMMU driver to use the generic IOVA allocator.
This driver now also benefits from the recent scalability
improvements in the IOVA code.
- preparations to use generic DMA mapping code in the Rockchip IOMMU
driver
- device tree adaption and conversion to use generic page-table code
for the MSM IOMMU driver
- an iova_to_phys optimization in the ARM-SMMU driver to greatly
improve page-table teardown performance with VFIO
- various other small fixes and conversions
