Must define how many entries and what they are if more than one.

Why is this a property? Does it change per board or instance? If not, it
should be implied by compatible.

Same question here.
If it remains, then you need:
items:
items:
- description: interrupt level (does that mean high/low?)
- description: bit index of enable register
Plus any constraints on the values if possible.

Looks like 'interrupt level' is just the index of the values? Why not
make this an array?
