This patch adds support to q6afe backend dais driver.


Isn't the list of backend DAIs platform-dependent?

dai links and connections between backend and front ends are platform dependent.

How will this look beyond HDMI? I'm having issues mapping this to
downstream.

ex:
For slimbus dais, we would have more entries of "struct snd_soc_dai_driver" in this file.

Basically these are the dais that are exposed by the dsp firmware.

Depending on the actually platform some of these dais would be setup accordingly.
