The mcux driver requires that the RX and TX buffers are the same
|
|
length, however the Zephyr spi interface allows them to be different.
|
|
When they are different, the mcux shim driver uses a local buffer. This
|
|
option defines the size of the local buffer.

This option configures what value to send when the TX buffer length is
|
|
less than the RX buffer length.
