This Kconfig has wrongly been added to defconfig files. It is not the right place for it. It has never been the right place for it. Drivers that need it should select the symbol in their Kconfig entries. Drop PINCTL from Kconfig.defconfig and add proper select at Kconfig.sam*.

|
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.
