that shouldn't be the case. Resources for EP1 are different than those
of EP2.

this makes no sense to me. Something else must be going on because
resources are different.

Something else is getting goofed up. Unfortunately I don't have HW to
test right now, but if you could send some trace output showing this
failure, then it would be easy to see what's going one. Just make sure
to use some gigantic buffer, e.g. 4096 KB (yes, 4 MB :-)

This is not what documentation says, neither is this what the commit
mentioned before (written by Synopsys :-) says. John, any comments here ?

Right, but look at what commit mentioned before says. Did you test that
specific case after this change of yours ?

ok, once I have HW again, I'll test this out. Unless John can help here.

dwc3 is almost completely silent nowadays. Debugging is done via
tracepoints only.

you really have 10k patches on top of
v4.4.0 ? _And_ it is dirty ? I need you
test with a tag from Linus or from the
Stable tree. This kernel I cannot trust
not to have changes on dwc3 ;-)
