I am working on adv7611 Linux Driver. The driver created a /dev/video for video.
My question is about audio:
Do I have another separate driver for adv7611 audio?
Or create another device for audio in the same driver?
Lars is correct -- the audio portion of the ADV7611 doesn't exist in our tree yet.
We (Lars) have been helping (minimally) someone who has a 4.0.0 kernel fork at:
that recently added support for the ADV7611 audio side.(link above)
the driver still needs a little work, but it might be easier to start with something that at least works on their platform (which looks like is iMx.6). They are working on putting things together, as a real patch, but they are away from keyboards the next few weeks.
Moved to Linux software drivers group
How is audio connected back to your SoC? (PCM/I2S or SPDIF?)
I don't believe that 2 drivers are necessary (at least I don't think so). Lars (who is the expert) is gone, but will be back tomorrow to answer your question.
I also assume you are working on the driver that is already upstream?
It looks like there is already some amount of audio support in that driver.
I can catch video upstream (by /dev/video1) but I don't know how to catch audio signal. Do you have any suggestion to test audio upstream signal? Thanks!
There is currently no audio support in the adv7604/adv7611 driver. There might be in the future but unfortunately I can't give any timelines when this will happen.
