Hi,

I've started playing a bit with the schemas, and one thing I cannot
wrap my head around at the moment is how to express things like one
property being required only by one compatible over a couple expressed
in the binding document.

Things like a reset property only being required for one particular SoC
for example.

Looking at the current examples, I could see two solutions, one where
we could condition a dependency on a propery value, and the other
where we could inherit another schema and just add more constraints.

I haven't found a way to find either though. Is it covered currently?

Thanks!
Maxime
