Interfacing a transceiver modem through I2S to SAI3 on iMX6ULL

[kmagi]

Hi All,

I am in the process of developing a dummy audio codec driver to interface a transceiver modem which is connected through I2S to SAI3 interface of iMX6ULL.

Here modem is acting as master and CPU slave as the modem CLK line is output.

Could you help me get some reference dummy audio codec driver and the device tree structure for the same?

Regards,

Kiran
