You can have a look at the FWTS source, there's some specific DT tests
there (we have one to ensure that when somebody creates a new machine,
they change the model name in the device tree from the reference
platform model name). Since FWTS uses the same device tree code as
everywhere, it's not too hard to follow, and the test report from FWTS
is pretty clear (and you can tell it to just run some tests).
