#include <dmic.h>

Data Fields
uint32_t	pcm_rate
	PCM sample rate of stream.

uint8_t	pcm_width
	PCM sample width of stream.

uint16_t	block_size
	PCM sample block size per transfer.

struct k_mem_slab *	mem_slab
	SLAB for DMIC driver to allocate buffers for stream.

Detailed Description

Configuration of the PCM streams to be output by the PDM hardware.

Note: if either pcm_rate or pcm_width is set to 0 for a stream, the stream would be disabled
