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.

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

914 # Add new SPI master controllers in alphabetical order above this line
917 comment "SPI Multiplexer support"
920 tristate "SPI multiplexer support"
923 This adds support for SPI multiplexers. Each SPI mux will be
924 accessible as a SPI controller, the devices behind the mux will appear
925 to be chip selects on this controller. It is still necessary to
926 select one or more specific mux-controller drivers.
929 # There are lots of SPI device types, with sensors and memory
930 # being probably the most widely used ones.
932 comment "SPI Protocol Masters"
935 tristate "User mode SPI device driver support"
937 This supports user mode SPI protocol drivers.
939 Note that this application programming interface is EXPERIMENTAL
940 and hence SUBJECT TO CHANGE WITHOUT NOTICE while it stabilizes.
942 config SPI_LOOPBACK_TEST
943 tristate "spi loopback test framework support"
946 This enables the SPI loopback testing framework driver
948 primarily used for development of spi_master drivers
949 and to detect regressions
952 tristate "Infineon TLE62X0 (for power switching)"
955 SPI driver for Infineon TLE62X0 series line driver chips,
956 such as the TLE6220, TLE6230 and TLE6240. This provides a
957 sysfs interface, with each line presented as a kind of GPIO
958 exposing both switch control and diagnostic feedback.
961 # Add new SPI protocol masters in alphabetical order above this line
967 # SLAVE side ... listening to other SPI masters
971 bool "SPI slave protocol handlers"
973 If your system has a slave-capable SPI controller, you can enable
974 slave protocol handlers.
978 config SPI_SLAVE_TIME
