Re: [PATCH v5 5/5] dt-bindings: audio-graph-port: add ch-map-idx property

Hi Rob

...

•  ch-map-idx:
  

•    description: It indicates index of ch_maps array for CPU / Codec if number of
  

•      CPU(N) / Codec(M) DAIs were not same in one dai-link. ch-map-idx is not needed if the
  

•      numbers were 1:M or N:1 or N=M. see soc.h::[dai_link->ch_maps Image sample] and
  

•      ${LINUX}/sound/soc/generic/audio-graph-card2-custom-sample.dtsi. It is good sample.
  

Why do we have a dtsi file hidden away here?

We have examples and actual users. Do we really need a 3rd way?

ASoC is supporting many type of (complex) connections, and Audio Graph Card2 is supporting all of them. There is no actual user who is using all type of connections. Thus there is no good sample for it.

Above is using all type of connections. And I'm using it for Audio Graph Card2 test purpose.

Thank you for your help !!
