The original binding only had 4 without a fallback. It's fine to add or
change, but note the changes in the commit msg. Are all of these really
each unique and not the same?


Ok I will note the changes in the commit for v2. And... yes, they're really
each unique and not the same, as these are exposing a reset controller of
their own (as well with different platform data in the driver).

Drop this and use 'unevaluatedProperties'.


Noted. Will do for v2.

Thanks!
