3 # SPI driver configuration
9 The "Serial Peripheral Interface" is a low level synchronous
10 protocol. Chips that support SPI can have data transfer rates
11 up to several tens of Mbit/sec. Chips are addressed with a
12 controller and a chipselect. Most SPI slaves don't support
13 dynamic device discovery; some are even write-only or read-only.
15 SPI is widely used by microcontrollers to talk with sensors,
16 eeprom and flash memory, codecs and various other controller
17 chips, analog to digital (and d-to-a) converters, and more.
18 MMC and SD cards can be accessed using SPI protocol; and for
19 DataFlash cards used in MMC sockets, SPI must always be used.
21 SPI is one of a family of similar protocols using a four wire
22 interface (select, clock, data in, data out) including Microwire
23 (half duplex), SSP, SSI, and PSP. This driver framework should
24 work with most such devices and controllers.

30 depends on DEBUG_KERNEL
32 Say "yes" to enable debug messaging (like dev_dbg and pr_debug),
33 sysfs, and debugfs support in SPI controller and protocol drivers.
36 # MASTER side ... talking to discrete SPI slave chips including microcontrollers
40 # bool "SPI Master Support"
44 If your system has an master-capable SPI controller (which
45 provides the clock and chipselect), you can enable that
46 controller and the protocol drivers for the SPI slave chips
52 bool "SPI memory extension"
54 Enable this option if you want to enable the SPI memory extension.
55 This extension is meant to simplify interaction with SPI memories
56 by providing a high-level interface to send memory-like commands.

892 tristate "Xtensa SPI controller for xtfpga"
893 depends on (XTENSA && XTENSA_PLATFORM_XTFPGA) || COMPILE_TEST
896 SPI driver for xtfpga SPI master controller.
898 This simple SPI master controller is built into xtfpga bitstreams
899 and is used to control daughterboard audio codec. It always transfers
900 16 bit words in SPI mode 0, automatically asserting CS on transfer
901 start and deasserting on end.

924 # Add new SPI master controllers in alphabetical order above this line
927 comment "SPI Multiplexer support"
930 tristate "SPI multiplexer support"
933 This adds support for SPI multiplexers. Each SPI mux will be
934 accessible as a SPI controller, the devices behind the mux will appear
935 to be chip selects on this controller. It is still necessary to
936 select one or more specific mux-controller drivers.
939 # There are lots of SPI device types, with sensors and memory
940 # being probably the most widely used ones.
942 comment "SPI Protocol Masters"
945 tristate "User mode SPI device driver support"
947 This supports user mode SPI protocol drivers.
949 Note that this application programming interface is EXPERIMENTAL
950 and hence SUBJECT TO CHANGE WITHOUT NOTICE while it stabilizes.
952 config SPI_LOOPBACK_TEST
953 tristate "spi loopback test framework support"
956 This enables the SPI loopback testing framework driver
958 primarily used for development of spi_master drivers
959 and to detect regressions
962 tristate "Infineon TLE62X0 (for power switching)"
965 SPI driver for Infineon TLE62X0 series line driver chips,
966 such as the TLE6220, TLE6230 and TLE6240. This provides a
967 sysfs interface, with each line presented as a kind of GPIO
968 exposing both switch control and diagnostic feedback.
971 # Add new SPI protocol masters in alphabetical order above this line
977 # SLAVE side ... listening to other SPI masters
