OK, you have multi DAI.
Then, you need to count is "port", not "endpoint".
So, your DT will be below.
You want to have is *1 for asoc_simple_card_get_dai_id().
You want to double check is *2 (maybe).
ports {
mcbsp3_port0: port@0 {
*1 reg = <0>;
cpu_dai3: endpoint {
dai-format = "dsp_a";
frame-master = <&cpcap_audio_codec1>;
bitclock-master = <&cpcap_audio_codec1>;
remote-endpoint = <&cpcap_audio_codec1>;
};
};
mcbsp3_port1: port@1 {
*1 reg = <1>;
cpu_dai_mdm: endpoint {
dai-format = "dsp_a";
*2 frame-master = <&cpcap_audio_codec1>;
*2 bitclock-master = <&cpcap_audio_codec1>;
remote-endpoint = <&mot_mdm6600_audio_codec0>;
};
};
};
