[I'm the author of that patch]
Can someone point me to the documentation of how to check a single
example against the dt schemata? I think I had that figured out how to
run the dt-checks over the whole tree in january but didn't bother with
warnings since the whole devtree was riddled with warnings at the time.
Docs on how to quickly check for warnings/errors would help me a lot. My
naive usage of dt-validate on an example yields a traceback, I've opened
a report on github because I think that even with gross mis-usage the
tool shouldn't traceback...

Thanks for your help and pointers.
Ralf
