An iommu driver for Qualcomm "B" family devices which do implement the ARM SMMU spec, but not in a way that arm-smmu can support.
(I initially added support to arm-smmu, but it was decided that approach was too intrusive and it would be cleaner to have a separate driver.) I should note that all the dependencies for this driver have been merged since 4.12, and it is the last thing needed for having another fully- enabled (gpu/display/video codec/etc) ARM device that is fully upstream. These patches can also be found at: git://people.freedesktop.org/~robclark/linux qcom_iommu-next https://cgit.freedesktop.org/~robclark/linux/log/?h=qcom_iommu-next No change since last time.
