tlv320aic3204 codec probe issue.

[kishan_dudhatra]

Hello folks,

I am working on the imx8mp custom board. tlv320aic3204 codec is connected to imx8mp over the I2C4 and SAI5 interface.

Here are my dts file changes :

 With the above dts changes I am getting the below error logs:

 Can someone see what I’m doing wrong or what I’m missing?

Hope you are doing well; I will be working in your support case.

The TLV320AIC3100 audio CODEC is not supported by default on our BSP. To use this CODEC to your system, you need to add a third-party driver provided by Texas Instruments and configure your device tree.

Unfortunately, there is no a guide to port this specific CODEC to the BSP. The references we have are the i.MX porting guide and EVK device tree (WM8960).

Maybe this thread could be helpful.

Best regards.
