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.

47 If your system has an master-capable SPI controller (which
48 provides the clock and chipselect), you can enable that
49 controller and the protocol drivers for the SPI slave chips
50 that are connected.

83 With a few GPIO pins, your system can bitbang the SPI protocol.
84 Select this to get SPI support through I/O pins (GPIO, parallel
85 port, etc). Or, some systems' SPI master controller drivers use
86 this code to manage the per-word or per-transfer accesses to the
87 hardware shift registers.
88
89 This is library code, and is automatically selected by drivers that
90 need it. You only need to select this explicitly to support driver

142 making it unusually slow for SPI. If your platform can inline
143 GPIO operations, you should be able to leverage that for better

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