[U-Boot] [PATCH v3 6/7] usb: ulpi: Extend the existing ulpi framework.

[Igor Grinberg <grinberg@compulab.co.il>]

Hi Govindraj,

I was about to ask Tom to reorder the patches while applying, but
there are still several things to fix.
I'm also fine with fixing these by a follow up patch (after merging this).

There are several comments, you missed to fix from previous version [1].
Please, fix those.

You should utilize the port_num variable here, right?
something like:
val |= (ulpi_vp->port_num & 0x7) << 24;

same here

haven't we aggreed, that this will be:
u32 port_num;
?

This is ulpi_vp now.
