Linus Torvalds 1daa56bcfd IOMMU Updates for Linux v5.5
Including:
 
 	- Conversion of the AMD IOMMU driver to use the dma-iommu code
 	  for imlementing the DMA-API. This gets rid of quite some code
 	  in the driver itself, but also has some potential for
 	  regressions (non are known at the moment).
 
 	- Support for the Qualcomm SMMUv2 implementation in the SDM845
 	  SoC.  This also includes some firmware interface changes, but
 	  those are acked by the respective maintainers.
 
 	- Preparatory work to support two distinct page-tables per
 	  domain in the ARM-SMMU driver
 
 	- Power management improvements for the ARM SMMUv2
 
 	- Custom PASID allocator support
 
 	- Multiple PCI DMA alias support for the AMD IOMMU driver
 
 	- Adaption of the Mediatek driver to the changed IO/TLB flush
 	  interface of the IOMMU core code.
 
 	- Preparatory patches for the Renesas IOMMU driver to support
 	  future hardware.
