Please CC me on this. I wanted to tackle this problem as well today. My
findings/conclusions so far:

* There is one driver bringing 'priority' directly to DT already: gpio-restart

* Watchdog priorities are board dependant

* Having the priorities clear at boot-time is safer than configuring them
  at run-time

* The linux scheme (0-255) shouldn't be enforced in DT

So, I wondered about a "priority" binding which just states "the higher,
the more important". Then any OS can decide what to do with it. In the
Linux case, this could be: sort them and give them priority 256 -
position_in_sorted_list.

Opinions?

Ack.
