| 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. |

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