I agree that the proposal looks reasonable (in terms of the ability to describe the sort of topologies that we will face) but I still don't understand what I need to do in e.g. my IOMMU driver to support this binding whilst continuing to support the existing iommus binding, which is relied upon to configure dma-mapping. Mark: how do you see this co-existing/merging with the current bindings? I don't think it's practical to throw away what we have and move over to something totally different all in one go, but there clearly *is* benefit in your proposal over the existing scheme.
