That doesn't really make sense. Maybe all 3 compatibles makes sense, but only if s/w understanding only one of the fallback compatibles would function without knowledge of the newer h/w. > + > + reg: > + maxItems: 1 > + > + '#index-cells': > + const: 1 > + description: Cells used to describe usb controller index.

That all can be a follow-up patch if you prefer or in this patch is fine.
