The hdmi driver provides a digital audio interface (DAI) which can be
used to transmit audio over the HDMI cable. The ASoC DAI component
driver provides just that functionality. A machine, platform, and (in
this case a dummy) codec component driver is also needed for a complete
ALSA device functionality.
Anyway, I look into Mark's suggestion of instantiating all the necessary
component drivers from the HDMI driver.
