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.

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.

802 for the Atom E6xx series and compatible with the Intel EG20T PCH.
805 tristate "Toshiba TXx9 SPI controller"
806 depends on GPIOLIB && (CPU_TX49XX || COMPILE_TEST)
808 SPI driver for Toshiba TXx9 MIPS SoCs
811 tristate "Socionext UniPhier SPI Controller"
812 depends on (ARCH_UNIPHIER || COMPILE_TEST) && OF
814 This enables a driver for the Socionext UniPhier SoC SCSSI SPI controller.
816 UniPhier SoCs have SCSSI and MCSSI SPI controllers.
817 Every UniPhier SoC has SCSSI which supports single channel.
818 Older UniPhier Pro4/Pro5 also has MCSSI which support multiple channels.
819 This driver supports SCSSI only.
821 If your SoC supports SCSSI, say Y here.
824 tristate "Analog Devices AD-FMCOMMS1-EBZ SPI-I2C-bridge driver"
827 Support for the SPI-I2C bridge found on the Analog Devices
828 AD-FMCOMMS1-EBZ board.
831 tristate "Xilinx SPI controller common module"
835 This exposes the SPI controller IP from the Xilinx EDK.
837 See the "OPB Serial Peripheral Interface (SPI) (v1.00e)"
838 Product Specification document (DS464) for hardware details.
840 Or for the DS570, see "XPS Serial Peripheral Interface (SPI) (v2.00b)"
843 tristate "Netlogic XLP SPI controller driver"
844 depends on CPU_XLP || ARCH_THUNDER2 || COMPILE_TEST
846 Enable support for the SPI controller on the Netlogic XLP SoCs.
847 Currently supported XLP variants are XLP8XX, XLP3XX, XLP2XX, XLP9XX
850 If you have a Netlogic XLP platform say Y here.
853 config SPI_XTENSA_XTFPGA
854 tristate "Xtensa SPI controller for xtfpga"
855 depends on (XTENSA && XTENSA_PLATFORM_XTFPGA) || COMPILE_TEST
858 SPI driver for xtfpga SPI master controller.
860 This simple SPI master controller is built into xtfpga bitstreams
861 and is used to control daughterboard audio codec. It always transfers
862 16 bit words in SPI mode 0, automatically asserting CS on transfer
863 start and deasserting on end.
866 tristate "Xilinx Zynq QSPI controller"
867 depends on ARCH_ZYNQ || COMPILE_TEST
869 This enables support for the Zynq Quad SPI controller
871 This controller only supports SPI memory interface.
873 config SPI_ZYNQMP_GQSPI
874 tristate "Xilinx ZynqMP GQSPI controller"
875 depends on (SPI_MASTER && HAS_DMA) || COMPILE_TEST
877 Enables Xilinx GQSPI controller driver for Zynq UltraScale+ MPSoC.
880 # Add new SPI master controllers in alphabetical order above this line
884 # There are lots of SPI device types, with sensors and memory
885 # being probably the most widely used ones.
887 comment "SPI Protocol Masters"
890 tristate "User mode SPI device driver support"
892 This supports user mode SPI protocol drivers.
894 Note that this application programming interface is EXPERIMENTAL
895 and hence SUBJECT TO CHANGE WITHOUT NOTICE while it stabilizes.
897 config SPI_LOOPBACK_TEST
898 tristate "spi loopback test framework support"
901 This enables the SPI loopback testing framework driver
903 primarily used for development of spi_master drivers
904 and to detect regressions
907 tristate "Infineon TLE62X0 (for power switching)"
910 SPI driver for Infineon TLE62X0 series line driver chips,
911 such as the TLE6220, TLE6230 and TLE6240. This provides a
912 sysfs interface, with each line presented as a kind of GPIO
913 exposing both switch control and diagnostic feedback.
916 # Add new SPI protocol masters in alphabetical order above this line
922 # SLAVE side ... listening to other SPI masters
926 bool "SPI slave protocol handlers"
928 If your system has a slave-capable SPI controller, you can enable
929 slave protocol handlers.
933 config SPI_SLAVE_TIME
934 tristate "SPI slave handler reporting boot up time"
936 SPI slave handler responding with the time of reception of the last
939 config SPI_SLAVE_SYSTEM_CONTROL
940 tristate "SPI slave handler controlling system state"
942 SPI slave handler to allow remote control of system reboot, power
943 off, halt, and suspend.
