DTS overlay for IMX8m Plus debix model B SCB

rcfcpereira — Fri, 05 Sep 2025 18:04:40 GMT

Need documentation to help create a device tree overlay file to be able to implement on SAI5, and also to integrate an ADC6140EVM-PDK from TI to use audio capture at a sample rate of 786 kHz.

Linux Ububtu 22.04.

Hello,

It turns out you do need to specify the channel in a multilane sai port. In any case., have to do this inside the codec:

dailink0_master: simple-audio-card,cpu {
sound-dai = <&sai5 0>;
};

There is no documentation about this. The binding documentation and examples I found online were all referencing one lane sai.

Hope this help.
