----------------------------------------------------------------
IOMMU Updates for Linux v5.4:

Including:

- Batched unmap support for the IOMMU-API

- Support for unlocked command queueing in the ARM-SMMU driver

- Rework the ATS support in the ARM-SMMU driver

- More refactoring in the ARM-SMMU driver to support hardware
implemention specific quirks and errata

- Bounce buffering DMA-API implementatation in the Intel VT-d driver
for untrusted devices (like Thunderbolt devices)

- Fixes for runtime PM support in the OMAP iommu driver

- MT8183 IOMMU support in the Mediatek IOMMU driver

- Rework of the way the IOMMU core sets the default domain type for
groups. Changing the default domain type on x86 does not require two
kernel parameters anymore.

- More smaller fixes and cleanups
