	  Enable support for mcux spi driver.

	int "Number of bytes in the local buffer"
	default 16
	help
	  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.

config SPI_MCUX_DUMMY_CHAR
	hex "Dummy character"
	default 0x00
	range 0x00 0xff
	help
	  This option configures what value to send when the TX buffer length is
	  less than the RX buffer length.
