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. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEr9jSbILcajRFYWYyK/BELZcBGuMFAl3hCC4ACgkQK/BELZcB GuN9QQ/+LFh2TdhtiemIakA/19nv1FTP719uje7vjX4gGBGD++NEzW7mBcAXSEnD rBta1GsD6N8h0fdT53Nw8cezQ1ldBomKG3j+mzcju7TcuRwebhCEQaxh2iWy+I6g cp6HxTu3G0E6Zy7wd+MWyJzvXa7MXV2p8iCDs7Dp8yEow+c55b4LAIoeRWx3rjsT rat29MuJ8TGLP6vOYHcpI+REGfda4rsog75980RIoOEuqRjMG6JPj9clPeakSNtQ Rl1EtgrDskbRCgDSujbzDMHAYRUKvdCuTuTM1De/GQO+GWYsOtzqBHkct67sGn9I H518Be9m4xfYyyktVM6K9bSpxzCOtor+u6LFOejufJN/7vL2qtePZX7EHL/ks8zh Mn80H/1ch1UcFcF9p7V7QCMUSyaiX/VWhgwWIdPf3CGrKVaLnQ8mkB82Zf0VNuQT OzcfJcVF+skhDkXdFL5xUkQtqqTHhpaK2CzvvTDAsR1KXMCc6mH/MT/9m+mOFQFK P+klgGdU5rVniru10k4pamT5LlLubRV0NBpaAiGr2R3dfyYyiS/D9FBSLanqO+JM AgSnmOSbl7y927DxufkVPH8M7TxSdtQVo7VoQFjSWE8B9bh4qU6MVV30enLvY0Fj g4DP+8srOvY0vNsWNiBe2JpldABGEAbumFt78g1WV2tFi1d/NUI= =ntaE -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull iommu updates from Joerg Roedel: - Conversion of the AMD IOMMU driver to use the dma-iommu code for imlementing the DMA-API.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
