I don't understand what does it mean. You can use in your driver
whatever headers you wish, I don't care about them.


noticed the same pattern in ../dt-bindings/sdtv-standarts.h for

Wrap your messages to match mailing list discussion style. There are no
defines used in DT. If there are, show me them in *THIS* or other
*upstreamed* (being upstreamed) patchset.

Whatever you have out of tree or "DO NOT MERGE" does not matter and does
not justify anything.
