I exactly meant that, maybe didn't make it clear enough. Of course, a seperate
driver would be better, but guess what will happen in most projects.

That was more a brainstorming question; there are notifiers which help
populating function-pointers which also can't be expressed in a device-tree.
I just wanted to make sure this approach doesn't get overlooked.

So, the solution for now is to simply add a default value and we can check
later if it can be modified at runtime?
