Looks like these are valid only for specific variant, so you should have
allOf:if:then disallowing other properties when not applicable. The same
applies for existing properties which might not exist on qca6390.

And it would be good to provide more information in the commit log about
the platforms where this is used, otherwise the context might not be
clear. Or maybe document that in the bindings file, not sure.
