What I am asking is, with audio-graph-card2, when you declare 1:N 
connection in DT bindings, how many DAI links you create in the driver.
Is it like the audio-graph-card2 driver parses the whole 1:N connection 
and creates only one DAI link in ASoC core or it breaks them into 
multiple links and create N+1 DAI links in ASoC core?

In other words,

1:N connection in DT == 1 DAI link in ASoC core?
Or
1:N connection in DT == N+1 DAI links in ASoC core?
