We have developed board which uses SMARC-sAMX6i module from Kontron. In SSI bus we have MAX98357A PCM input class D audio amplifier which takes either I^2S or TDM data

and acts as slave for SSI bus. We are using kernel 3.14 so which are the stpes to get SSI bus and maxim working?


- dts configure settings so we can write raw data to /dev/i2s device




- Do we need create ALSA driver for that or is there driver already in kernel which have to activate in device tree?



- Something else ?
