# For a description of the syntax of this configuration file,
# see misc/tools/kconfig-language.txt.
#
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.
