I'm 99.9999999999 % sure this is misnamed.

"Inter" means in-between two things.
"Intra" means inside of one thing.

So "intraframe" means inside of one frame "interframe" would mean power collapsing in-between two frames, which is what I think this does.

And I'd still rather be adding inter-frame power-collapse to as many different versions of the existing silicon and new silicon as opposed to segregating it off in a new driver.

I'm assuming that more than sm8550 supports it since @ the end of the day this is a firmware feature to power-collapse during an active session when we aren't busy.
