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 tristate "Analog Devices AD-FMCOMMS1-EBZ SPI-I2C-bridge driver"
807 Support for the SPI-I2C bridge found on the Analog Devices
808 AD-FMCOMMS1-EBZ board.
811 tristate "Xilinx SPI controller common module"
815 This exposes the SPI controller IP from the Xilinx EDK.
817 See the "OPB Serial Peripheral Interface (SPI) (v1.00e)"
818 Product Specification document (DS464) for hardware details.
820 Or for the DS570, see "XPS Serial Peripheral Interface (SPI) (v2.00b)"
823 tristate "Netlogic XLP SPI controller driver"
824 depends on CPU_XLP || ARCH_THUNDER2 || COMPILE_TEST
826 Enable support for the SPI controller on the Netlogic XLP SoCs.
827 Currently supported XLP variants are XLP8XX, XLP3XX, XLP2XX, XLP9XX
830 If you have a Netlogic XLP platform say Y here.
833 config SPI_XTENSA_XTFPGA
834 tristate "Xtensa SPI controller for xtfpga"
835 depends on (XTENSA && XTENSA_PLATFORM_XTFPGA) || COMPILE_TEST
838 SPI driver for xtfpga SPI master controller.
840 This simple SPI master controller is built into xtfpga bitstreams
841 and is used to control daughterboard audio codec. It always transfers
842 16 bit words in SPI mode 0, automatically asserting CS on transfer
843 start and deasserting on end.
845 config SPI_ZYNQMP_GQSPI
846 tristate "Xilinx ZynqMP GQSPI controller"
847 depends on SPI_MASTER && HAS_DMA
849 Enables Xilinx GQSPI controller driver for Zynq UltraScale+ MPSoC.
852 # Add new SPI master controllers in alphabetical order above this line
856 # There are lots of SPI device types, with sensors and memory
857 # being probably the most widely used ones.
859 comment "SPI Protocol Masters"
862 tristate "User mode SPI device driver support"
864 This supports user mode SPI protocol drivers.
866 Note that this application programming interface is EXPERIMENTAL
867 and hence SUBJECT TO CHANGE WITHOUT NOTICE while it stabilizes.
869 config SPI_LOOPBACK_TEST
870 tristate "spi loopback test framework support"
873 This enables the SPI loopback testing framework driver
875 primarily used for development of spi_master drivers
876 and to detect regressions
879 tristate "Infineon TLE62X0 (for power switching)"
882 SPI driver for Infineon TLE62X0 series line driver chips,
883 such as the TLE6220, TLE6230 and TLE6240. This provides a
884 sysfs interface, with each line presented as a kind of GPIO
885 exposing both switch control and diagnostic feedback.
888 # Add new SPI protocol masters in alphabetical order above this line
894 # SLAVE side ... listening to other SPI masters
898 bool "SPI slave protocol handlers"
900 If your system has a slave-capable SPI controller, you can enable
901 slave protocol handlers.
905 config SPI_SLAVE_TIME
906 tristate "SPI slave handler reporting boot up time"
908 SPI slave handler responding with the time of reception of the last
911 config SPI_SLAVE_SYSTEM_CONTROL
912 tristate "SPI slave handler controlling system state"
914 SPI slave handler to allow remote control of system reboot, power
915 off, halt, and suspend.
