Hi Linus,

This time there are a few patches from the driver-core tree in this
pull-request, which you already pulled from Greg. The reason is that I
had to merge the driver-core-next branch to get the device dependency
link patches into my tree, because the changes for the Exynos IOMMU
driver in this pull-request depend on them.

This is also the reason for a minor merge conflict in
drivers/base/power/main.c caused by the IOMMU updates this time.

Also the ACPI/IORT patches make changes outside of the IOMMU code. These
changes were acked by their respective maintainers.

With this disclaimer in mind, here is the meat:

The following changes since commit 3e5de27e940d00d8d504dfb96625fb654f641509:

----------------------------------------------------------------
IOMMU Updates for Linux v4.10

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
