Are there applications that actually need these controls? I do not
feel comfortable exposing such low-level controls to user-space in this way.

This is a recurring topic (if and how to expose low-level functionality) and
I have some ideas on how to solve this in the future. But for now I prefer it
if these are not exported yet.

BTW: only patch 1/6 is cross-posted to the linux-media list. I'm not sure if
that was intentional or an accident.

Regards,

        Hans
