A delay of 0 implies that software continually polls this zone, thus
consuming an entire CPU. Is this really what you want?

This zone (and the other) is missing the required (per the binding
documentation) trips and cooling-maps sub-nodes.

I've also sent a query in response to the thermal-zones binding so see
whether or not it can be fixed so that software doesn't bind against the
node name, but rather against a compatible property like almost
everything else. Let's see what the response is there before reposting
this patch.
