In v1, Morimoto-san wondered whether the alias is really needed, but you
haven't addressed his question.

While aliases can be useful in DT source files, using aliases like this imposes
hardcoded instance numbers, which is something we try to avoid these days.
Also, this puts a hard requirement on the presence of the alias in DT, which
should be documented in the DT bindings.

when I'm talking to journalists I just say "programmer" or something like that.
