Hi,

I am working on an imx8mn-based board with an ES9080 codec and I am trying to get EASCR to work. (The ES9080 driver is not upstreamed yet).

Audio playback works fine via simple-audio-card and here are my changes to get EASRC to work:

• sound-ess {

• compatible = "simple-audio-card";
  

• simple-audio-card,name = "ess-audio";
  

• simple-audio-card,format = "left_j";
  

• simple-audio-card,frame-master = <&s2cpu>;
  

• simple-audio-card,bitclock-master = <&s2cpu>;
  

• s2cpu: simple-audio-card,cpu {
  

• 	sound-dai = <&sai2>;
  

• 	dai-tdm-slot-num = <8>;
  

fsl-asoc-card does not take the number of slots into account.

I have sent a patch adding support for it.

Now I can get audio output and will be running more tests.

Thanks
