Yup, I knew those features but am unaware of any situation where they drive out
IEC958 - they just run I2S, SPI, TDM (?)
Also, IMO, it would make more sense to implement it as a Virtual card
of ASoC(outside of linux/sound/soc/), with number of devices equalling
the number
of shifters registered.

Thank you.
