in order to keep my word, I offer this version this time.

The "host1" port (AKA the dwc2 port that isn't the OTG port) on rk3288
has a hardware errata that causes everything to get confused when we get
a remote wakeup. We'll use the reset that's in the CRU to reset the
port when it's in a bad state.
Note that we add the reset to bo
Hi, the implementation of Doug is thought quick but the Herring

So I suggest to accept this idea. It may be better if dropped
