config SPI
	bool "SPI Driver Support"
	default n
	---help---
		This selection enables selection of common SPI options.  This option
		should be enabled by all platforms that support SPI interfaces.
		See include/nuttx/spi/spi.h for further SPI driver information.

if SPI
config SPI_OWNBUS
	bool "SPI single device"
	default n
	---help---
		Set if there is only one active device on the SPI bus.  No locking or
		SPI configuration will be performed. It is not necessary for clients to
		lock, re-configure, etc..

config SPI_EXCHANGE
	bool "SPI exchange"
	default y
	---help---
		Driver supports a single exchange method (vs a recvblock() and
		sndblock() methods).

config SPI_CMDDATA
	bool "SPI CMD/DATA"
	default n
	---help---
		Devices on the SPI bus require out-of-band support to distinguish
		command transfers from data transfers.  Such devices will often support
		either 9-bit SPI (yech) or 8-bit SPI and a GPIO output that selects
		between command and data.
