What does "for full HDMI audio support" mean? What's the partial support? =)

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.

Best regards,
Jyri
