Great, thanks for the reply. It's very helpful to know that you're
looking at it even if you haven't had time to do a full review yet.

Note: if any of my patches are wrong or redundant to patches that
you've developed and tested, I'm happy to take your patches instead.
;)

Note that patches 1 - 11 have already landed in our tree and thus are
getting additional exposure and testing. IMHO those are all ready for
prime time. Assuming there are no huge issues, it would be handy if
those 11 patches landed as-is (or almost as-is), but that's just me
being selfish so I don't need to revert / reland new versions. :-P


Also note that the period of time where I can devote this much time to
dwc2 is coming soon to an end since I have to go on to work on other
things. If there are major issues or easy fixes I will certainly be
able to help with those things (I'll still be around), but I won't be
able to devote days to tracking down weird problems or testing
rewrites. ;-)
