I'm not clear what this is (especially given the source selection below)
but it looks like it should be a mute control?

This I'd expect to be tied into machine driver configuration, either DT
properties or TDM slot configuration - it's not something that looks
like it's something you'd want to control at runtime.

This looks like it should be a DAPM control or possibly a TDM slot
configuration - look at how the Arizona devices handle routing from
multiple TDM slots for the DAPM version.

Yes, each channel of enable and disable control. 
I will update this also configured by TDM slot configuration.

I will update this with either TDM slot configuration and DT properties.

This is for Current Sensing and Voltage sensing slot selection. I will update this as DT properties.
