If you introduce API thinking about the name before actually introducing
it is a good idea in general. (OK, the name doesn't become part of the
(binary) dt API, but we don't even agree about its semantic here.)

And IMHO a bad name with a good documentation isn't good enough.
Otherwise we can better just agree on using plain numbers in the .dts
files.

Best regards
Uwe
