|
When RTIO is used 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.
