"gen3" and "gen2" don't carry much meaning on their own (SH2 is gen2 of
SuperH?). Furthermore, revision info should immediately follow the comma.

"renesas,rcar-gen3-cmm" and "renesas,rcar-gen2-cmm"?

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
