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.

803 depends on GPIOLIB && (CPU_TX49XX || COMPILE_TEST)
805 SPI driver for Toshiba TXx9 MIPS SoCs
808 tristate "Socionext UniPhier SPI Controller"
809 depends on (ARCH_UNIPHIER || COMPILE_TEST) && OF
811 This enables a driver for the Socionext UniPhier SoC SCSSI SPI controller.
813 UniPhier SoCs have SCSSI and MCSSI SPI controllers.
814 Every UniPhier SoC has SCSSI which supports single channel.
815 Older UniPhier Pro4/Pro5 also has MCSSI which support multiple channels.
816 This driver supports SCSSI only.
818 If your SoC supports SCSSI, say Y here.
821 tristate "Analog Devices AD-FMCOMMS1-EBZ SPI-I2C-bridge driver"
824 Support for the SPI-I2C bridge found on the Analog Devices
825 AD-FMCOMMS1-EBZ board.
828 tristate "Xilinx SPI controller common module"
832 This exposes the SPI controller IP from the Xilinx EDK.
834 See the "OPB Serial Peripheral Interface (SPI) (v1.00e)"
835 Product Specification document (DS464) for hardware details.
837 Or for the DS570, see "XPS Serial Peripheral Interface (SPI) (v2.00b)"
840 tristate "Netlogic XLP SPI controller driver"
841 depends on CPU_XLP || ARCH_THUNDER2 || COMPILE_TEST
843 Enable support for the SPI controller on the Netlogic XLP SoCs.
844 Currently supported XLP variants are XLP8XX, XLP3XX, XLP2XX, XLP9XX
847 If you have a Netlogic XLP platform say Y here.
850 config SPI_XTENSA_XTFPGA
851 tristate "Xtensa SPI controller for xtfpga"
852 depends on (XTENSA && XTENSA_PLATFORM_XTFPGA) || COMPILE_TEST
855 SPI driver for xtfpga SPI master controller.
857 This simple SPI master controller is built into xtfpga bitstreams
858 and is used to control daughterboard audio codec. It always transfers
859 16 bit words in SPI mode 0, automatically asserting CS on transfer
860 start and deasserting on end.
863 tristate "Xilinx Zynq QSPI controller"
864 depends on ARCH_ZYNQ || COMPILE_TEST
866 This enables support for the Zynq Quad SPI controller
868 This controller only supports SPI memory interface.
870 config SPI_ZYNQMP_GQSPI
871 tristate "Xilinx ZynqMP GQSPI controller"
872 depends on (SPI_MASTER && HAS_DMA) || COMPILE_TEST
874 Enables Xilinx GQSPI controller driver for Zynq UltraScale+ MPSoC.
877 # Add new SPI master controllers in alphabetical order above this line
881 # There are lots of SPI device types, with sensors and memory
882 # being probably the most widely used ones.
884 comment "SPI Protocol Masters"
887 tristate "User mode SPI device driver support"
889 This supports user mode SPI protocol drivers.
891 Note that this application programming interface is EXPERIMENTAL
892 and hence SUBJECT TO CHANGE WITHOUT NOTICE while it stabilizes.
894 config SPI_LOOPBACK_TEST
895 tristate "spi loopback test framework support"
898 This enables the SPI loopback testing framework driver
900 primarily used for development of spi_master drivers
901 and to detect regressions
904 tristate "Infineon TLE62X0 (for power switching)"
907 SPI driver for Infineon TLE62X0 series line driver chips,
908 such as the TLE6220, TLE6230 and TLE6240. This provides a
909 sysfs interface, with each line presented as a kind of GPIO
910 exposing both switch control and diagnostic feedback.
913 # Add new SPI protocol masters in alphabetical order above this line
919 # SLAVE side ... listening to other SPI masters
923 bool "SPI slave protocol handlers"
925 If your system has a slave-capable SPI controller, you can enable
926 slave protocol handlers.
930 config SPI_SLAVE_TIME
931 tristate "SPI slave handler reporting boot up time"
933 SPI slave handler responding with the time of reception of the last
936 config SPI_SLAVE_SYSTEM_CONTROL
937 tristate "SPI slave handler controlling system state"
939 SPI slave handler to allow remote control of system reboot, power
940 off, halt, and suspend.
