Hi
According to Documentation/devicetree/bindings/sound/audio-graph-card.txt it should be something like this: &mcbsp3 { #sound-dai-cells = <0>; pinctrl-names = "default"; pinctrl-0 = <&mcbsp3_pins>; status = "okay";
ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; cpu_dai3: endpoint@0 { dai-format = "dsp_a"; frame-master = <&cpcap_audio_codec1>; bitclock-master = <&cpcap_audio_codec1>; remote-endpoint = <&cpcap_audio_codec1>; }; cpu_dai_mdm: endpoint@1 { dai-format = "dsp_a"; frame-master = <&cpcap_audio_codec1>; bitclock-master = <&cpcap_audio_codec1>; remote-endpoint = <&mot_mdm6600_audio_codec0>; }; };}; };
(snip)
I guess Morimoto-san can explain if he carries out of tree patches to get the described setup working on top of mainline...
# I think ALSA ML is rejecting mail (?), # I couldn't find original patch / Mail and Discussion at ALSA ML. # Thus, I'm not 100% understanding what is the issue...
I confirmed attached patch on my local platform (= Renesas ULCB + KF board), and it works well for me on at least v5.5 kernel.

It seems 1 sound card DAI number is limited by SNDRV_MINOR(). Because of this size limit, total 8 DAI seems maximam. So, this patch removes HDMI so far.
