Adding all of them would cause even more churn when adding support for
a new SoC... There are already more than 700 "renesas," compatible
values documented that are not directly matched by drivers.
Nowadays we have "make dtbs_check", so if a DTS doesn't conform to the
binding, it will be flagged.

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