Hi all, Prompted by some discussion around the questionable usefulness of iommu_present() for SoC topologies, I took a look at what was left to finish off the intention of making groups mandatory. Turns out it wasn't much, so here it is. As well as the general rationalisation aspect, between this and the probe-deferral changes in 4.12, we should now be able to rely on the presence of a group unambiguously indicating whether a given device is associated with an IOMMU or not.
