Hi Martin,

But that should happen even before starting the link training, if the AUX is
not up yet, then we should not go ahead and do the clock recovery phase at all,
why not wait here for 250ms and then find some way to just fail without
attempting link training.

I am trying to find out at what point can we first check for dp aux
transactions and wait longer to try again?
