Hi all,
In this series, I add several new interfaces for chipidea driver,
they are mainly for system configuration adjustment. The USB
performance may be improved with these configuration changing,
but each vendor driver owner needs to consult with your IC

The zero-length packet is the sendor tells the receiver that there
