Re: [PATCH v10 0/9] ASoC: tda998x: add a codec to the HDMI transmitter

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

slave encoder private data as the device private data

(Russell King)
v6:
- extend the HDMI CODEC instead of using a specific CODEC
v5:
- use the TDA998x private data instead of a specific area
for the CODEC interface
- the CODEC is TDA998x specific (Mark Brown)
v4:
- remove all the TDA998x specific stuff from the CODEC
- move the EDID scan from the CODEC to the TDA998x
- move the CODEC to sound/soc (Mark Brown)
- update the audio_sample_rate from the EDID (Andrew Jackson)
v3: fix bad rate (Andrew Jackson)
v2: check double stream start (Mark Brown)
