I think what Rob meant to point out is that graph.txt now contains a
mention that the file has been moved to a more central location, which
is the dt-schema repository. So instead of referencing the graph.txt,
which then redirects to the graph.yaml in dt-schema, it'd be better to
directly reference graph.yaml from dt-schema.

That said, I'm not aware of a good or standard way to make such a
reference. Perhaps in this case, given that the rt5659 binding is not
very large, you can convert the file to json-schema first and then use
standard json-schema references for this.
