This determines how many buffers the driver should allocate and
|
|
reserve for the DMA engine. The memory slab used with the DMIC
|
|
API should provide at least one more buffer than this value, since
|
|
a buffer will always be in the RX queue.

This sets the size of the RX buffer queue for the DMIC. Up to this
|
|
many buffers may be queued by the DMIC once it is triggered, before
|
|
the application must read buffers to avoid data being dropped.
