The entire reason I created the <dt-bindings/> directory (rather than
just putting *.h into e.g. arch/arm/boot/dts) was to provide a place to
share binding-defined constants between the DT files and drivers that
implement that binding. It's certainly my opinion that if/when *.dts
move out of the kernel, the <dt-bindings/> directory should continue to
be present in the kernel, and take updates mirrored from the upstream
binding repo.
