[PATCH 0/3] usb: dwc2: params revert and rework

[John Youn]

Hi Felipe,

This reverts and fixes a few commits that are queued on your
testing/next, removing the previously added DT bindings, and the code
that reads them in.

The feedback was that IP validation is not reason enough to add these.
So we'll leave them out for now.

Regards,
John

these are still in testing/next, so I can actually still drop
them. I'm applying only patch 3/3, please make sure it all looks good on
testing/next.

Ok thanks. There were merge issues when I did that locally so I
figured I'd give you the reverts.

Checked and looks good.

John
