It is expected to be included into dtsi and into rpmhpd driver (only). However I'd also suggest adding some generic prefix (e.g. RPMHPD_CX).

Don't bother yourself with this, we've already dragged you through some bindings mess ;) Dmitry just noticed that a happy coincidence occured and we could swap out SM8[234]_50 indices with these ones and they would still match.
