Can it actually do mono? Maybe at probe time you could look at audio flags
from your previous patch and, e.g., for SPDIF set channels_min to 2?

That's the "smallest max," yes. With some other interfaces (I2S, DSD) it
can support up to 8 channels...

Hm, in the datasheet I see supported frequencies 32kHz to 192kHz. And if
you promise support for multiple frequencies, don't you want to implement
.hw_params? Besides, not all of these frequencies will be available,
depending on your supplied clock and your willingness to implement
downsampling.
