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>;
- dai-tdm-slot-width = <32>;
- };
-
- simple-audio-card,codec {
- sound-dai = <&es9080>;
- };
+ sound-es9080 {
+ compatible = "fsl,imx-audio-es9080";
+ model = "es9080-with-easrc";
+ audio-cpu = <&sai2>;
+ audio-codec = <&es9080>;
+ audio-asrc = <&easrc>;
};
};

The es9080-with-easrc card is registered, but after running
'speaker-test' no
audio output is present.
Is there a way to use the EASRC driver with the simple-audio-card
without
touching fsl-asoc-card.c? That would be preferable.
Would you have any suggestions as to what may be missing to get EASRC to
work?
Thanks,
Fabio Estevam
