SPI I2S on Jetson nano



we use 40-pin GPIO header (SPI0 & I2S4) to connect a module.
we need porting a driver to control it.
the driver implement spi and i2s data transmit.
how to set the driver device tree?

is it possible get i2s data without using alsa command in jeston nano?

Have a check below document for i2s
