[Sound-open-firmware] Multiple configurations per DAI in topology

Ah, thanks for reporting this.

There are two issues here:
1. we really want the topology to contain more than one configuration, 
and let the kernel pass the relevant one based on current usage so that 
the correct bclk, mclk etc are used. This is not supported currently. I 
just re-added this issue for the Linux kernel and topoplogy.

2. the PR 630 https://github.com/thesofproject/sof/issues/630 is about 
combining or splitting information between DAIs, or possibly from a 
single TDM DAI. This is more of a firmware logic part, not really 
something related to the configuration of the hardware registers 
controlling the interface.

Does this help?
