General informations

The Linux kernel configuration item CONFIG_SPI:

• prompt: SPI support
• type: tristate
• depends on: CONFIG_HAS_IOMEM
• defined in drivers/spi/Kconfig
• found in Linux Kernels: from 2.6.16 release still available on 2.6.34 release

Help text

The "Serial Peripheral Interface" is a low level synchronous protocol. Chips that support SPI can have data transfer rates up to several tens of Mbit/sec. Chips are addressed with a controller and a chipselect. Most SPI slaves don't support dynamic device discovery; some are even write-only or read-only.

SPI is widely used by microcontrollers to talk with sensors, eeprom and flash memory, codecs and various other controller chips, analog to digital (and d-to-a) converters, and more. MMC and SD cards can be accessed using SPI protocol; and for DataFlash cards used in MMC sockets, SPI must always be used.

SPI is one of a family of similar protocols using a four wire interface (select, clock, data in, data out) including Microwire (half duplex), SSP, SSI, and PSP. This driver framework should work with most such devices and controllers.
