Hi Linus,

The following changes since commit 31f4f5b495a62c9a8b15b1c3581acd5efeb9af8c:

Linux 5.4-rc7 (2019-11-10 16:17:15 -0800)

are available in the Git repository at:

----------------------------------------------------------------
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.
