| When RTIO is use with SPI each driver holds a context with which blocking |
| API calls use to perform SPI transactions. This queue needs to be as deep |
| as the longest set of spi_buf_sets used, where normal SPI operations are |
| used (equal length buffers). It may need to be slightly deeper where the |
| spi buffer sets for transmit/receive are not always matched equally in |
| length as these are transformed into normal transceives. |
