Error while registering the sound card on iMX6 sabrelite board

[anilghadiya]

Hi,

I am trying to register a sound card from the machine driver of the codec adau1701 which is connected via i2c..

What should be the value of .cpu_dai_name and  .platform_name in the dai link.

I am using iMX6-sabrelite board with trusty(3.10.17) SD card image.

Thanks in Advance,

Hi,

"and SoC as i2s pins of SoC are already connected to sgtl5000 codec" Do you mean that you are using the same pins for both codecs?

Thanks,

Alejandro

Hi,

What i meant is that SoC's i2s pins are connected to the sgtl5000 so, we we can not establish the i2s interface between adau1701 codec and SoC.

Thanks and Regards,

Maybe I am misunderstanding, but you cannot use 2  i2S codecs with the same MPU pins.

Hi,

Can you share the code of your codec and the modifications you have performed?

I suggest you to use as reference the code for the SGTL500 source/sound/soc/mxs/mxs-sgtl5000.c

If you are getting any error please provide the details.

Best Regards,

Hi,

Thanks for the reply. Attached is the codec and machine driver files for adau1701.

When i try to insert the machine driver, it fails with the error code (-517). Have a look at screen-shot for the details.

I am connecting the codec via I2C to the board. Is it required to establish any other link between SoC and the codec?

Is it possible to connect any codec to the iMX board and use it as one of the dai links while registering the sound card?

Hi,

Sorry forgot to attach the code in previous post. PFA.

Hi,

I have checked and the error -517 corresponds to

#define EPROBE_DEFER  517  /* Driver requests probe retry */

And after checking your dtsi file I noticed that in your sound node you are using a phandle to the sgtl-5000. Therefore it tries to register the codec sgtl 5000.

I believe that you will have to modify the adau1701.c which does not use the .compatible or the dts. I checked in more recent kernels and the adau1701.c is already using the dts.

You may find that file useful.

Hi,

Were you able to make it work?

Hi,

We are not able to establish the i2S link between codec(adau1701) and SoC as i2s pins of SoC are already connected to sgtl5000 codec.

And as per the ASoC, there has to be at least  one DAI link between codec and SoC. If you have any idea on how to establish the i2s link between iMX6 boardand any codec, please do share it with us.

Thanks and Regards,

Anil
