That much is correct.

That is not true. GMI_AD13 / PH5 / 61 is a signal that pulls up all of
USB1 VBUS, USB3 VBUS, and GMI_AD15, which as far as I can tell is
entirely unrelated to USB in any way.

This part of the change should be removed. I know you mentioned that
downstream does this, but that means very little; there are many
mistakes there.

Aside from that, this patch looks fine.
