| help |
| 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. |

| help |
| 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. |
