That's one of the most redundant subjects I saw. You basically used four
words for one meaning. These are not exactly synonyms, but they all are
either imprecise or meaning the same.

Subject: drop second/last, redundant "Bindings YAML schemas". The
"dt-bindings" prefix is already stating that these are bindings.

What do you wrap here? Are you sure this is a wrapper? I think this is
just USB controller?
