playing with dai1 will have issue.
I guess so because you are using strange settings...
What do you want to do ?
this is just an example setting to reproduce the issue with current
mainline kernel,
We have enabled TDM Split and Ex-Split mode in our kernel,
and SSI(U)'s dma address diffs based on the BUSIF it is using,
so have a single dma data struct per rsnd_ssi will cause issue when
SSI isn't working with BUSIF0.
Do you have any suggestion to address this issue?
Thanks,
Jiada
Best regards
