We also have DAC and ADC drivers (up to 16 bits @ 64MS/s, via DMA),
that would be nice to put in the "right" place  - I don't think that
drivers/char is the right place, nor drivers/misc - I also don't think
that /adc is a descriptive place for DAC or mixed signal front ends
(MxFE).

What userspace interface do your drivers have?

Right now, it is a little rudimentary char interface, it needs a little care
to be a bit more general purpose, but it suited needs of what the people who
were using it.

I would be interested in having a detailed discussion/random thoughts on
this - what is the best way to expose these types of devices?

Since you ask for random thoughts:

IO of data streams from or to a DAC/ADC is essentially what soundcards do.
I'm wondering if these cards are similar enough to use alsa, and if using
that interface would ease or hinder programming the driver.
