There is no user of this new header, so I don't agree. Please send
either full work or link your other upstreamed patchset. Anything sent
as "DO NOT MERGE" does not count because it is not an user.

Without the DTS user I claim that you do not bind here anything...

Copying or symlinking entire header into bindings does not help us to
understand what is exactly a binding here.

For example, maybe you encode runtime information into DT (don't do
this) and that's why you need these defines... Or maybe your block has
some capabilities. Dunno, patch was not tested, is defined as do not
merge and is not explaining any of these.

Therefore, please provide complete set of users ready to be merged, test
your patches, provide rationale why this is supposed to be a binding and
why do you think it represents hardware configuration, not OS policy or
runtime configuration.

Best regards,
Krzysztof
