Hi, I am working on a project where I am supposed to send audio data from an Nvidia Xavier NX that runs L4T v4.9 to a Cirrus Logic CS47L35 chip. I have to send control signals over SPI and audio data over I2S. I came across this machine driver file /nvidia/sound/soc/tegra-alt/machine_drivers/tegra_machine_driver_mobile.c, but I am not sure how I can use this file. So what modifications are required to be made here, or is there any other file that I can use?
Thanks,
Abhigyan
