ADAU7002 device configuration not working - IMX8ULP-EVK9

[dhruvinrajpura]

I am attempting to connect a microphone to the A core of the IMX8ULP-EVK9 using the ADAU7002 IC. I've added the ADAU7002 node to my DTS file, but I'm encountering the following error.

[ 21.860836] platform sound-adau7002: deferred probe pending

I also checked this node with sai5 as well.

Can anyone check on this?...

Thanks in advance.

Hello,

The ADAU7002 is not supported by default on our BSP. To use this converter in your system, maybe you need to add a third-party driver.

Unfortunately, there is not a guide to port this specific device to the BSP. The references we have are the i.MX porting guide and EVK device tree (WM8960).

Maybe these links could be helpful:

sound/soc/codecs/adau7002.c

Documentation/devicetree/bindings/sound/adi,adau7002.yaml

Best regards.
