An iommu driver for Qualcomm "B" family devices which do not completely implement the ARM SMMU spec. These devices have context-bank register layout that is similar to ARM SMMU, but no global register space (or at least not one that is accessible).
There are a couple vaguely unrelated patches to add venus and gpu dt nodes, so that we have something to wire up the iommu to. These patches apply on top of some in-flight patches to support IOMMU probe deferral. You can find full branch on top of linux-next here: git://people.freedesktop.org/~robclark/linux next-20170307-db410c-qcom-smmu-3-venus or github if you prefer: https://github.com/freedreno/kernel-msm/commits/next-20170307-db410c-qcom-smmu-3-venus Compared to previous patchset, there have been some (mostly binding related) cleanups. Also fixed some other-config related build issues that kbuild robot spotted.
