This split into multiple files *really* doesn't seem like it adds
anything but complexity, the small amount of reuse just doesn't seem
worth it.

What's this configuring?  I didn't notice it on the CODEC driver as the
function wasn't exported IIRC.

This should be done by using the TDM slot API - the slot length is one
of the parameters.

Do this from the driver.

No need to do this, everything defaults on.
