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.

806 depends on PCI && (X86_32 || MIPS || COMPILE_TEST)
808 SPI driver for the Topcliff PCH (Platform Controller Hub) SPI bus
809 used in some x86 embedded processors.
811 This driver also supports the ML7213/ML7223/ML7831, a companion chip
812 for the Atom E6xx series and compatible with the Intel EG20T PCH.
815 tristate "Toshiba TXx9 SPI controller"
816 depends on GPIOLIB && (CPU_TX49XX || COMPILE_TEST)
818 SPI driver for Toshiba TXx9 MIPS SoCs
821 tristate "Socionext UniPhier SPI Controller"
822 depends on (ARCH_UNIPHIER || COMPILE_TEST) && OF
824 This enables a driver for the Socionext UniPhier SoC SCSSI SPI controller.
826 UniPhier SoCs have SCSSI and MCSSI SPI controllers.
827 Every UniPhier SoC has SCSSI which supports single channel.
828 Older UniPhier Pro4/Pro5 also has MCSSI which support multiple channels.
829 This driver supports SCSSI only.
831 If your SoC supports SCSSI, say Y here.
834 tristate "Analog Devices AD-FMCOMMS1-EBZ SPI-I2C-bridge driver"
837 Support for the SPI-I2C bridge found on the Analog Devices
838 AD-FMCOMMS1-EBZ board.
841 tristate "Xilinx SPI controller common module"
845 This exposes the SPI controller IP from the Xilinx EDK.
847 See the "OPB Serial Peripheral Interface (SPI) (v1.00e)"
848 Product Specification document (DS464) for hardware details.
850 Or for the DS570, see "XPS Serial Peripheral Interface (SPI) (v2.00b)"
853 tristate "Netlogic XLP SPI controller driver"
854 depends on CPU_XLP || ARCH_THUNDER2 || COMPILE_TEST
856 Enable support for the SPI controller on the Netlogic XLP SoCs.
857 Currently supported XLP variants are XLP8XX, XLP3XX, XLP2XX, XLP9XX
860 If you have a Netlogic XLP platform say Y here.
863 config SPI_XTENSA_XTFPGA
864 tristate "Xtensa SPI controller for xtfpga"
865 depends on (XTENSA && XTENSA_PLATFORM_XTFPGA) || COMPILE_TEST
868 SPI driver for xtfpga SPI master controller.
870 This simple SPI master controller is built into xtfpga bitstreams
871 and is used to control daughterboard audio codec. It always transfers
872 16 bit words in SPI mode 0, automatically asserting CS on transfer
873 start and deasserting on end.
876 tristate "Xilinx Zynq QSPI controller"
877 depends on ARCH_ZYNQ || COMPILE_TEST
879 This enables support for the Zynq Quad SPI controller
881 This controller only supports SPI memory interface.
883 config SPI_ZYNQMP_GQSPI
884 tristate "Xilinx ZynqMP GQSPI controller"
885 depends on (SPI_MASTER && HAS_DMA) || COMPILE_TEST
887 Enables Xilinx GQSPI controller driver for Zynq UltraScale+ MPSoC.
890 # Add new SPI master controllers in alphabetical order above this line
894 # There are lots of SPI device types, with sensors and memory
895 # being probably the most widely used ones.
897 comment "SPI Protocol Masters"
900 tristate "User mode SPI device driver support"
902 This supports user mode SPI protocol drivers.
904 Note that this application programming interface is EXPERIMENTAL
905 and hence SUBJECT TO CHANGE WITHOUT NOTICE while it stabilizes.
907 config SPI_LOOPBACK_TEST
908 tristate "spi loopback test framework support"
911 This enables the SPI loopback testing framework driver
913 primarily used for development of spi_master drivers
914 and to detect regressions
917 tristate "Infineon TLE62X0 (for power switching)"
920 SPI driver for Infineon TLE62X0 series line driver chips,
921 such as the TLE6220, TLE6230 and TLE6240. This provides a
922 sysfs interface, with each line presented as a kind of GPIO
923 exposing both switch control and diagnostic feedback.
926 # Add new SPI protocol masters in alphabetical order above this line
932 # SLAVE side ... listening to other SPI masters
936 bool "SPI slave protocol handlers"
938 If your system has a slave-capable SPI controller, you can enable
939 slave protocol handlers.
943 config SPI_SLAVE_TIME
944 tristate "SPI slave handler reporting boot up time"
946 SPI slave handler responding with the time of reception of the last
949 config SPI_SLAVE_SYSTEM_CONTROL
950 tristate "SPI slave handler controlling system state"
952 SPI slave handler to allow remote control of system reboot, power
953 off, halt, and suspend.
