Hi,
Have you done anything about the tda998x audio support lately?
I was thinking of taking a shot at this now that I finally seem to have
some time for it. However, if you are just about to send another series
I'll wait for that first and see what makes the most sense after that.
My plan is to do something really simple first. No graph bindings or
anything fancy like that. Just a minimal dt-binding to for audio pin
configuration and use simple-card for the rest. I still try to make it
possible to support spdif and i2s at the same time, but I can not test
it as I do not have such HW.
I also try to make the ASoC part as generic as possible, so that it
could be reused by other HDMI encoders with spdif or i2s interface.
Best regards,
Jyri

v3: fix bad rate (Andrew Jackson)
v2: check double stream start (Mark Brown)
