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: git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git tags/iommu-updates-v5.5 for you to fetch changes up to 9b3a713feef8db41d4bcccb3b97e86ee906690c8: Merge branches 'iommu/fixes', 'arm/qcom', 'arm/renesas', 'arm/rockchip', 'arm/mediatek', 'arm/tegra', 'arm/smmu', 'x86/amd', 'x86/vt-d', 'virtio' and 'core' into next (2019-11-12 17:11:25 +0100) ---------------------------------------------------------------- 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. ---------------------------------------------------------------- Biju Das (2):
