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

Matt LaPlante3cb2fcc2006-11-30 05:22:59 +010018 SPI is widely used by microcontrollers to talk with sensors,
David Brownell8ae12a02006-01-08 13:34:19 -080019 eeprom and flash memory, codecs and various other controller
20 chips, analog to digital (and d-to-a) converters, and more.
21 MMC and SD cards can be accessed using SPI protocol; and for
22 DataFlash cards used in MMC sockets, SPI must always be used.
23
24 SPI is one of a family of similar protocols using a four wire
25 interface (select, clock, data in, data out) including Microwire
26 (half duplex), SSP, SSI, and PSP. This driver framework should
27 work with most such devices and controllers.

645 SPI driver for Infineon TLE62X0 series line driver chips,
646 such as the TLE6220, TLE6230 and TLE6240. This provides a
647 sysfs interface, with each line presented as a kind of GPIO
648 exposing both switch control and diagnostic feedback.
