This seems completely backwards: Why would you list the masters for an IOMMU in the IOMMU node?
The master should have a standard property pointing to the IOMMU instead.
We don't have a generic binding for IOMMUs yet it seems, but the time is overdue to make one.
Consider this NAKed until there is a generic binding for IOMMUs that all relevant developers have agreed to.
