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.

808 # There are lots of SPI device types, with sensors and memory
809 # being probably the most widely used ones.
811 comment "SPI Protocol Masters"
814 tristate "User mode SPI device driver support"
816 This supports user mode SPI protocol drivers.
818 Note that this application programming interface is EXPERIMENTAL
819 and hence SUBJECT TO CHANGE WITHOUT NOTICE while it stabilizes.
821 config SPI_LOOPBACK_TEST
822 tristate "spi loopback test framework support"
825 This enables the SPI loopback testing framework driver
827 primarily used for development of spi_master drivers
828 and to detect regressions
831 tristate "Infineon TLE62X0 (for power switching)"
834 SPI driver for Infineon TLE62X0 series line driver chips,
835 such as the TLE6220, TLE6230 and TLE6240. This provides a
836 sysfs interface, with each line presented as a kind of GPIO
837 exposing both switch control and diagnostic feedback.

846 # SLAVE side ... listening to other SPI masters
850 bool "SPI slave protocol handlers"
852 If your system has a slave-capable SPI controller, you can enable
853 slave protocol handlers.
857 config SPI_SLAVE_TIME
858 tristate "SPI slave handler reporting boot up time"
860 SPI slave handler responding with the time of reception of the last
863 config SPI_SLAVE_SYSTEM_CONTROL
864 tristate "SPI slave handler controlling system state"
866 SPI slave handler to allow remote control of system reboot, power
867 off, halt, and suspend.
