However there are also configurations which make use of TDM number, in which case expected behavior would be to have string in form of SSP:TDM - see implementation of avs_i2s_platform_register() in sound/soc/intel/avs/pcm.c. Implement custom function, which parses string and make use of it when parsing topology. While at it make sure that we generate dynamic names only if there is no multiple SSPs or TDMs defined.
