2 # SPI driver configuration
8 The "Serial Peripheral Interface" is a low level synchronous
9 protocol. Chips that support SPI can have data transfer rates
10 up to several tens of Mbit/sec. Chips are addressed with a
11 controller and a chipselect. Most SPI slaves don't support
12 dynamic device discovery; some are even write-only or read-only.
14 SPI is widely used by microcontrollers to talk with sensors,
15 eeprom and flash memory, codecs and various other controller
16 chips, analog to digital (and d-to-a) converters, and more.
17 MMC and SD cards can be accessed using SPI protocol; and for
18 DataFlash cards used in MMC sockets, SPI must always be used.
20 SPI is one of a family of similar protocols using a four wire
21 interface (select, clock, data in, data out) including Microwire
22 (half duplex), SSP, SSI, and PSP. This driver framework should
23 work with most such devices and controllers.
28 bool "Debug support for SPI drivers"
29 depends on DEBUG_KERNEL
31 Say "yes" to enable debug messaging (like dev_dbg and pr_debug),
32 sysfs, and debugfs support in SPI controller and protocol drivers.
35 # MASTER side ... talking to discrete SPI slave chips including microcontrollers
39 # bool "SPI Master Support"
43 If your system has an master-capable SPI controller (which
44 provides the clock and chipselect), you can enable that
45 controller and the protocol drivers for the SPI slave chips
51 bool "SPI memory extension"
53 Enable this option if you want to enable the SPI memory extension.
54 This extension is meant to simplify interaction with SPI memories
55 by providing a high-level interface to send memory-like commands.

804 Older UniPhier Pro4/Pro5 also has MCSSI which support multiple channels.
805 This driver supports SCSSI only.
807 If your SoC supports SCSSI, say Y here.
810 tristate "Analog Devices AD-FMCOMMS1-EBZ SPI-I2C-bridge driver"
813 Support for the SPI-I2C bridge found on the Analog Devices
814 AD-FMCOMMS1-EBZ board.
817 tristate "Xilinx SPI controller common module"
821 This exposes the SPI controller IP from the Xilinx EDK.
823 See the "OPB Serial Peripheral Interface (SPI) (v1.00e)"
824 Product Specification document (DS464) for hardware details.
826 Or for the DS570, see "XPS Serial Peripheral Interface (SPI) (v2.00b)"
829 tristate "Netlogic XLP SPI controller driver"
830 depends on CPU_XLP || ARCH_THUNDER2 || COMPILE_TEST
832 Enable support for the SPI controller on the Netlogic XLP SoCs.
833 Currently supported XLP variants are XLP8XX, XLP3XX, XLP2XX, XLP9XX
836 If you have a Netlogic XLP platform say Y here.
839 config SPI_XTENSA_XTFPGA
840 tristate "Xtensa SPI controller for xtfpga"
841 depends on (XTENSA && XTENSA_PLATFORM_XTFPGA) || COMPILE_TEST
844 SPI driver for xtfpga SPI master controller.
846 This simple SPI master controller is built into xtfpga bitstreams
847 and is used to control daughterboard audio codec. It always transfers
848 16 bit words in SPI mode 0, automatically asserting CS on transfer
849 start and deasserting on end.
852 tristate "Xilinx Zynq QSPI controller"
853 depends on ARCH_ZYNQ || COMPILE_TEST
855 This enables support for the Zynq Quad SPI controller
857 This controller only supports SPI memory interface.
859 config SPI_ZYNQMP_GQSPI
860 tristate "Xilinx ZynqMP GQSPI controller"
861 depends on (SPI_MASTER && HAS_DMA) || COMPILE_TEST
863 Enables Xilinx GQSPI controller driver for Zynq UltraScale+ MPSoC.
866 # Add new SPI master controllers in alphabetical order above this line
870 # There are lots of SPI device types, with sensors and memory
871 # being probably the most widely used ones.
873 comment "SPI Protocol Masters"
876 tristate "User mode SPI device driver support"
878 This supports user mode SPI protocol drivers.
880 Note that this application programming interface is EXPERIMENTAL
881 and hence SUBJECT TO CHANGE WITHOUT NOTICE while it stabilizes.
883 config SPI_LOOPBACK_TEST
884 tristate "spi loopback test framework support"
887 This enables the SPI loopback testing framework driver
889 primarily used for development of spi_master drivers
890 and to detect regressions
893 tristate "Infineon TLE62X0 (for power switching)"
896 SPI driver for Infineon TLE62X0 series line driver chips,
897 such as the TLE6220, TLE6230 and TLE6240. This provides a
898 sysfs interface, with each line presented as a kind of GPIO
899 exposing both switch control and diagnostic feedback.
902 # Add new SPI protocol masters in alphabetical order above this line
908 # SLAVE side ... listening to other SPI masters
912 bool "SPI slave protocol handlers"
914 If your system has a slave-capable SPI controller, you can enable
915 slave protocol handlers.
919 config SPI_SLAVE_TIME
920 tristate "SPI slave handler reporting boot up time"
922 SPI slave handler responding with the time of reception of the last
925 config SPI_SLAVE_SYSTEM_CONTROL
926 tristate "SPI slave handler controlling system state"
928 SPI slave handler to allow remote control of system reboot, power
929 off, halt, and suspend.
