Rob,

Can you give me a pointer on what this message is saying?  I don't
undertsand the YAML language, and I cannot get my machine to generate
the same messages you're seeing.

I have installed yamllint, and I have run the above line, but when I
run make dt_binding_check it fails to finish script even before I add
this new binding.  If I revert the Makefile back to before the
implementation of yamllint, it works, but doesn't show the error.
When I restore the Makefile, it runs but it doesn't show the error.
Once I do a make clean, and run the dt_binding_check again, it fails
to finish with the following error

make[1]: *** [Documentation/devicetree/bindings/Makefile:59:
Documentation/devicetree/bindings/processed-schema-examples.json]
Error 123

It appears as if the processed-schema-examples.json is not generated at all.

When I revert back to the older makefile, it appears that file is
generated, but when I restore the makefile to the current version and
run it again, it doesn't show the dtschema warnings/errors you see.
I am guessing it's because the processed-schema-examples.json isn't
being generated correctly after I run make clean.

Do you have any ideas what might be missing from my build machine?
