You know, I'm not sure this is helpful, as if we have to go and
describe what the chip supports, a paragraph for dual ouput mode would
be required as well. The bindings already document that the chip
supports single/dual input/output modes, maybe you can just add rules
that prescribes how to populate the endpoints, for both input and
output modes?

You can drop this empty line.
