I already commented on version 2 of the patch, but that was missing
the linux-arm-kernel mailing list on Cc, so I'll reply here as well
with a more general remark:

We are currently planning the removal of non-DT board support for a
lot of platforms, and spitz is currently on the list I have noted down for
getting removed in early 2023, see the thread at

https://lore.kernel.org/linux-arm-kernel/b8372253-abf6-5eee-f9cd-788bc5f24be2@zonque.org/

Are you actively using this machine, and planning to keep using it
in the future? Are you interested in working on or testing a DT
conversion?
