ASoC: ics43432: add CMM-4030D-261 support
Despite minimal datasheet differences, the driver seems
perfectly compatible with CMM-4030D-261.
Tested CMM-4030D-261 to work with this changes:
/ {
cmm4030d: cmm4030d {
#sound-dai-cells = <0>;
compatible = "cui,cmm-4030d-261";
};
sound_mic {
compatible = "simple-audio-card";
simple-audio-card,name = "i2s mem mic";
simple-audio-card,format = "i2s";
simple-audio-card,bitclock-master = <&sound_master>;
simple-audio-card,frame-master = <&sound_master>;
sound_master: simple-audio-card,cpu {
sound-dai = <&ssi2>;
system-clock-frequency = <2822400>;
};
simple-audio-card,codec {
sound-dai = <&cmm4030d>;
};
};
};
Audio has been captured and tested successfully by:
arecord -D "hw:1,0" -f S24_LE > test.wav
aplay test.wav
