The problem is the "^.*$" patterns to match child node names also match 
properties like 'phandle'. Ideally, you'd have some pattern to match on 
for the node names.

There is work-around doing:

"^.*$":
  if:
    type: object
  then:
    properties:
      ...

But I much prefer to see node names updated. '-pins$' is a common 
pattern.
