Yes, I got what you meant here and after some homework also found the example of this. You are trying to convey something similar to what is done within "outmixer_event()" function of sound/soc/codecs/wm8991.c (at lest the condition checking part), right?
No, that's not a user visible control that's part of the internal DAPM power management stuff. You're looking for struct snd_kcontrol_new stuff.
All you're doing is trying to restrict the values that can be set on a control dynamically.
I think, it is more about restricting access to a set of controls dynamically based of enable/disable of some other control(s).
The state of another control is one example of a dynamic source of information.
