Unless there was a newer revision of [1], the cx pd will most likely
be unused due to it not being specified under opp_pmdomain.

I don't see it in sm8350 releases and it's hard to tell out of thin air what values
should be in there.. Unless qcom decides to share some documentation ;)
Besides that, I don't see the driver part being merged neither in linux-next, nor media-next but I may be looking at the wrong tree.
