No worries. It's just important to have the discussions in the mailing
list so that others can see and participate.

Ok, so the board file for your device is missing. I'll try to find it. I
see that Alexander already opened a bug about this:

https://bugzilla.kernel.org/show_bug.cgi?id=215625

Let's continue the discussion there, I'll report my findings in the bug
report.

Can you file a separate bug report about that as well, please? Also try
to explain in detail how you see the slowdown, preferable with timing
info.
