We're currently in the process of defining a generic binding for IOMMUs.

While the smmu-masters property was copied from an existing binding,
I think we will end up migrating away from that towards a common way
to express those things, and we shouldn't add another one doing this
in a nonstandard way. Please have a look at the latest discussion
about the iommu binding using #iommu-cells and a reference from the
master to the iommu and see if you can migrate your code to use that.
