So I'll use snd_pcm_hw_constraint_eld.

For eld updates and jack handling I could try to go forward with
Russell's notification prototype from the "[RFC,V2,0/5] another generic
audio hdmi codec proposal" thread:
https://patchwork.kernel.org/patch/7339011/

Or are you saying there shouldn't be a Mediatek specific HDMI sound
driver at all and this should be handled by generic code?
