Hmmm. Why would the board have control over whether VBUS is asserted if
the port isn't intended to operate in OTG mode?

Perhaps power-saving? In that case, I wonder if representing this as a
regulator rather than as a VBUS GPIO would make more sense?

But irrespective of those questions, I'm inclined to think the patch is
probably OK.
