Agreed,

We are happy pick up the torch on this, but I'd like to try and hear from

Joakim first before we do.  The patch set is his, so I'd like to give him the
opportunity.  I think he's the only one that can add a truly proper description
as well because he mentioned that this includes a "few more fixes" than just
the one we ran into.  I'd rather hear from him than try to reverse engineer
what was being addressed.

Joakim, if you are still watching the thread, would you like to take a stab

at it?  If I don't hear from you in a couple days, we'll pick up the torch and do
what we can.

I am far away from this now and still on 4.19. I don't mind if you tweak

tweak the patches for better "upstreamability"

Even better would be to migrate to the chipidea driver, I am told just a few
tweaks are needed but this is probably something NXP should do as they
have access to other SOC's using chipidea.

I agree with this direction but the problem was with bandwidth.  As this controller was only used on legacy platforms, it is harder to justify new effort on it now.

Legacy? All PPC is legacy and not supported now?
