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.

803 for the Atom E6xx series and compatible with the Intel EG20T PCH.
806 tristate "Toshiba TXx9 SPI controller"
807 depends on GPIOLIB && (CPU_TX49XX || COMPILE_TEST)
809 SPI driver for Toshiba TXx9 MIPS SoCs
812 tristate "Socionext UniPhier SPI Controller"
813 depends on (ARCH_UNIPHIER || COMPILE_TEST) && OF
815 This enables a driver for the Socionext UniPhier SoC SCSSI SPI controller.
817 UniPhier SoCs have SCSSI and MCSSI SPI controllers.
818 Every UniPhier SoC has SCSSI which supports single channel.
819 Older UniPhier Pro4/Pro5 also has MCSSI which support multiple channels.
820 This driver supports SCSSI only.
822 If your SoC supports SCSSI, say Y here.
825 tristate "Analog Devices AD-FMCOMMS1-EBZ SPI-I2C-bridge driver"
828 Support for the SPI-I2C bridge found on the Analog Devices
829 AD-FMCOMMS1-EBZ board.
832 tristate "Xilinx SPI controller common module"
836 This exposes the SPI controller IP from the Xilinx EDK.
838 See the "OPB Serial Peripheral Interface (SPI) (v1.00e)"
839 Product Specification document (DS464) for hardware details.
841 Or for the DS570, see "XPS Serial Peripheral Interface (SPI) (v2.00b)"
844 tristate "Netlogic XLP SPI controller driver"
845 depends on CPU_XLP || ARCH_THUNDER2 || COMPILE_TEST
847 Enable support for the SPI controller on the Netlogic XLP SoCs.
848 Currently supported XLP variants are XLP8XX, XLP3XX, XLP2XX, XLP9XX
851 If you have a Netlogic XLP platform say Y here.
854 config SPI_XTENSA_XTFPGA
855 tristate "Xtensa SPI controller for xtfpga"
856 depends on (XTENSA && XTENSA_PLATFORM_XTFPGA) || COMPILE_TEST
859 SPI driver for xtfpga SPI master controller.
861 This simple SPI master controller is built into xtfpga bitstreams
862 and is used to control daughterboard audio codec. It always transfers
863 16 bit words in SPI mode 0, automatically asserting CS on transfer
864 start and deasserting on end.
867 tristate "Xilinx Zynq QSPI controller"
868 depends on ARCH_ZYNQ || COMPILE_TEST
870 This enables support for the Zynq Quad SPI controller
872 This controller only supports SPI memory interface.
874 config SPI_ZYNQMP_GQSPI
875 tristate "Xilinx ZynqMP GQSPI controller"
876 depends on (SPI_MASTER && HAS_DMA) || COMPILE_TEST
878 Enables Xilinx GQSPI controller driver for Zynq UltraScale+ MPSoC.
881 # Add new SPI master controllers in alphabetical order above this line
885 # There are lots of SPI device types, with sensors and memory
886 # being probably the most widely used ones.
888 comment "SPI Protocol Masters"
891 tristate "User mode SPI device driver support"
893 This supports user mode SPI protocol drivers.
895 Note that this application programming interface is EXPERIMENTAL
896 and hence SUBJECT TO CHANGE WITHOUT NOTICE while it stabilizes.
898 config SPI_LOOPBACK_TEST
899 tristate "spi loopback test framework support"
902 This enables the SPI loopback testing framework driver
904 primarily used for development of spi_master drivers
905 and to detect regressions
908 tristate "Infineon TLE62X0 (for power switching)"
911 SPI driver for Infineon TLE62X0 series line driver chips,
912 such as the TLE6220, TLE6230 and TLE6240. This provides a
913 sysfs interface, with each line presented as a kind of GPIO
914 exposing both switch control and diagnostic feedback.
917 # Add new SPI protocol masters in alphabetical order above this line
923 # SLAVE side ... listening to other SPI masters
927 bool "SPI slave protocol handlers"
929 If your system has a slave-capable SPI controller, you can enable
930 slave protocol handlers.
934 config SPI_SLAVE_TIME
935 tristate "SPI slave handler reporting boot up time"
937 SPI slave handler responding with the time of reception of the last
940 config SPI_SLAVE_SYSTEM_CONTROL
941 tristate "SPI slave handler controlling system state"
943 SPI slave handler to allow remote control of system reboot, power
944 off, halt, and suspend.
