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.
