	help
	  The driver can support two operation modes.
	  1. A HW registers dump blob that is passed via IPC
	  2. DAI tokens those describe the use case PCM format
	  and PDM bus and microphone parameters

config DAI_INTEL_DMIC_NHLT
	bool "Use NHLT DMIC blob"
	help
	  All registers configuration is retrieved from blob. The
	  number of channels, sample rate, and PCM format are
	  defined in the blob and there are no runtime made
	  configuration choices.

config DAI_INTEL_DMIC_TPLG_PARAMS
	bool "Use parameters from topology - WIP"
	help
	  All registers configuration is computed on the fly
	  based on use case and microphone datasheet parameters
	  and topology defined PCM format. The parameters are
	  easy to to customize in the topology.
