In this scenario your GSM modem is essentially functioning as a CODEC
within ASoC. The simplest thing to do is set up a dummy DAI in your
machine driver for the GSM modem, register that at startup and then set
up a dai_link for that as normal. You can then address the two streams
individually as devices on the card.
The OpenMoko is doing something similar with its bluetooth chipset,
though that is connected to a second DAI on the CODEC rather than the
CPU.
