I think we should be very careful to get the device tree syntax right
at first. So if you have a good representation of the data in the device
tree but don't handle all possible cases in the kernel yet, that's ok.

E.g. the kernel code can assume for now that the device tree has only
one spinlock controller node. We can fix that later when we actually
need more, but we would not easily be able to fix the device trees
after the fact.
