Main changes include: * Preparation for MSI support for SMMUv3 devices (full support will likely come in 4.4, since the IRQ core needs some work to support non-PCI devices). * A couple of minor fixes in the SMMUv3 driver * Support for the dma-coherent propery on SMMUv1/2 devices * Removal of the DMA API abuse for flushing page tables out to a non-coherent walker. This raised some questions about the DMA API Documentation, so I've put these last in the series in case you decide not to include them (but I think they're a welcome clean-up). Please pull, Will --->8 The following changes since commit cbfe8fa6cd672011c755c3cd85c9ffd4e2d10a6f: Linux 4.2-rc4 (2015-07-26 12:26:21 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/will/linux.git for-joerg/arm-smmu/updates for you to fetch changes up to f5b831907da3e64bfb0288089a5c07124266b1a5: iommu/io-pgtable: Remove flush_pgtable callback (2015-08-06 14:35:40 +0100) ---------------------------------------------------------------- Marc Zyngier (2): iommu/arm-smmu: Fix enabling of PRIQ interrupt iommu/arm-smmu: Fix MSI memory attributes to match specification Robin Murphy (9): iommu/arm-smmu: Sort out coherency iommu/io-pgtable-arm: Allow appropriate DMA API use iommu/arm-smmu: Clean up DMA API usage iommu/arm-smmu: Clean up DMA API usage iommu/ipmmu-vmsa: Clean up DMA API usage iommu/io-pgtable-arm: Centralise sync points iommu/arm-smmu: Remove arm_smmu_flush_pgtable() iommu/arm-smmu: Remove arm_smmu_flush_pgtable() iommu/io-pgtable: Remove flush_pgtable callback Will Deacon (2): iommu/arm-smmu: Limit 2-level strtab allocation for small SID sizes iommu/arm-smmu: Treat unknown OAS as 48-bit .../devicetree/bindings/iommu/arm,smmu.txt | 6 + drivers/iommu/Kconfig | 3 +- drivers/iommu/arm-smmu-v3.c | 66 +++++------ drivers/iommu/arm-smmu.c | 45 +++----- drivers/iommu/io-pgtable-arm.c | 126 +++++++++++++++------ drivers/iommu/io-pgtable.h | 9 +- drivers/iommu/ipmmu-vmsa.c | 19 +--- 7 files changed, 157 insertions(+), 117 deletions(-)
