I didn't not thought about that. I'm not sure to understand how this is
done for a gpio for example. Is this done by setting the link property
manually ?

If that's the case, I suppose we can somehow add a link property on the
input side to the output side to achieve that. The other way seem not
possible due to the fact the output side has a dynamically allocated
list of inputs.

It would be a solution, but I don't think we want this ?
