One or the other :)
On PCs there is support for HDMI audio within the HDA subsystem so it
would seem reasonable to add the support in ASoC if the hardware shares
anything with the rest of the audio hardware in the SoC. It may also
make sense to provide a driver which presents both video and audio
interfaces, depending on how the hardware is structured.
If the hardware doesn't share anything with the other audio hardware
then it might be as easy to just implement outside ASoC as a regular
ALSA driver since HDMI "CODECs" are usually the TVs or other remote
devices that are plugged in to the system rather than a component of the
system itself so the CODEC/CPU split of ASoC isn't such a clear benefit.
