AVS driver operates with granular audio card division in mind. Super-card approach (e.g.: I2S, DMIC and HDA DAIs combined) is deprecated in favour of individual cards - one per each device. This provides necessary dynamism, especially for configurations with number of codecs present and makes it easier to survive auxiliary devices failures - one card failing to probe does not prevent others from succeeding.
All boards spawned by AVS are unregistered on ->remove(). This includes dummy codecs such as DMIC.
As all machine boards found in sound/soc/intel/boards are irreversibly tied to 'super-card' approach, new boards are going to be introduced. This temporarily increases number of boards available under /intel directory until skylake-driver becomes deprecated and removed.
