I'm sorry but isn't this slightly disagreeing with the "writing
bindings" doc pointed in v1? It says,

* DO use fallback compatibles when devices are the same as or a subset
  of prior implementations.

I believe we fall in the "devices are the same" category, so I would
have myself wrote a similar binding here with a compatible matching
them all, plus a hardware-implementation-specific compatible as well;
just in case.

Thanks,
Miquèl
