This is good - an ASoC codec driver should expose as much functionality
of the codec as possible and let user space configure it at runtime.
See for example the WM8900 or WM8990 drivers for examples of codecs with
fairly complex audio routing.

It's still useful to keep people in CCs - it's not so bad with
alsa-devel but it does help to ensure that things don't get missed on
high volume mailing lists.
