My quick idea is using "peripheral" flag. I think we can set it on soc_bind_dai_link() ? And we can use it like below
for_each_dais(dai, xxx) { if(!dai->peripheral) /* non Peripheral == CPU portion */
if(dai->peripheral) /* Peripheral == Codec portion */}
But what do you think about this idea/naming etc ? I want to investigate more about Codec <-> Codec connection, which driver is using it ? Especially CPU portion
I'm thinking it might be better to keep the list ordered in the DAI link - that will scale up better with multi-drop links. What's going to be a bit more tricky sometimes is working out which end of the link is a CPU DAI but we can probably take a good guess easily enough on order neutral bindings and things liken simple-card already know explicitly.
