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kernel, gives you outdated entries.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.

79XX sounds weird. Are you sure you are not using wildcards (which are
not allowed)?

I already saw AFE, why it cannot be part of existing bindings?

This list is odd. 79xx, 7981? So it is wildcard?

Why this is variable?

Drop assigned-clocks
