Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC.  It might happen, that command when run on an older
kernel, gives you outdated entries.  Therefore please be sure you base
your patches on recent Linux kernel.

This missed also DT list so it means it won't be tested.

I think the problem of missing compatible is still not solved...
