So, this is a nit, but worth considering...

Somehow we've developed this habit of putting labels at the top of each
file; I really think that they just add clutter and are best left out.
Without the label, this reference:

...can just be written as "Please see
Documentation/devicetree/bindings/ABI.rst".  The cross-reference link
will be generated as expected, and readers of the plain-text docs don't
have to go grepping to find the reference.

Thanks,
