One use-case there is the ability to describe groups of masters behind a multi-master IOMMU but which must be part of the same domain (i.e. an iommu_group). This is useful for presenting devices to a guest with a virtual SMMU, where the physical devices share a stage-2 context. With your binding, does this simply mean determining the set of master IDs in the group, then describing the complete set for each master?
