Sorry for the delay. Things got busy for me recently.

So your platform has multiple ports. Do you use UTMI or ULPI phy?

I forgot another thing, the phy reset we're doing now doesn't apply to
ULPI phys. We may need to teach HCRST to dwc3, this may not look clean.

Hi Lisheng,

Did you see any reported issue before your change were applied? If not,
perhaps we should revert the changes related to soft-reset for this.

Thanks,
Thinh
