Subject: [git pull] IOMMU Updates for Linux v5.9
Hi Linus,
there is a tiny conflict with your tree because of the Kconfig changes
this time. Please see my attached resolution. With that in mind:
The following changes since commit 92ed301919932f777713b9172e525674157e983d:
Linux 5.8-rc7 (2020-07-26 14:14:06 -0700)
are available in the Git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git tags/iommu-updates-v5.9
for you to fetch changes up to e46b3c0d011eab9933c183d5b47569db8e377281:
Merge tag 'arm-smmu-updates' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux into next (2020-07-29 14:47:37 +0200)
----------------------------------------------------------------
IOMMU Updates for Linux v5.9
Including:
- Removal of the dev->archdata.iommu (or similar) pointers from
most architectures. Only Sparc is left, but this is private to
Sparc as their drivers don't use the IOMMU-API.
- ARM-SMMU Updates from Will Deacon:
- Support for SMMU-500 implementation in Marvell
Armada-AP806 SoC
- Support for SMMU-500 implementation in NVIDIA Tegra194 SoC
- DT compatible string updates
- Remove unused IOMMU_SYS_CACHE_ONLY flag
- Move ARM-SMMU drivers into their own subdirectory
- Intel VT-d Updates from Lu Baolu:
- Misc tweaks and fixes for vSVA
- Report/response page request events
- Cleanups
- Move the Kconfig and Makefile bits for the AMD and Intel
drivers into their respective subdirectory.
- MT6779 IOMMU Support
- Support for new chipsets in the Renesas IOMMU driver
- Other misc cleanups and fixes (e.g. to improve compile test
coverage)
