This is another attempt to upstream the code to unwedge the rk3288's "host" USB port when it sees a remote wakeup. Previously I attempted this [1] and it appears that Randy Li made some attempts too [2] which resulted in at least the PHY bindings for the USB PHY landing as well as the USB PHY support. Nice! Hopefully this addresses previous comments and could land this time?
