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?

I'm not saying that they are not supported, but they are in maintenance only mode.
