4# NOTE: the reason this doesn't show SPI slave support is mostly that
5# nobody's needed a slave side API yet. The master-role API is not
6# fully appropriate there, so it'd need some thought to do well.

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 +0100[diff] [blame]18 SPI is widely used by microcontrollers to talk with sensors,

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.

48 provides the clock and chipselect), you can enable that
49 controller and the protocol drivers for the SPI slave chips

153 With a few GPIO pins, your system can bitbang the SPI protocol.
154 Select this to get SPI support through I/O pins (GPIO, parallel
155 port, etc). Or, some systems' SPI master controller drivers use
156 this code to manage the per-word or per-transfer accesses to the
157 hardware shift registers.

159 This is library code, and is automatically selected by drivers that
160 need it. You only need to select this explicitly to support driver
161 modules that aren't part of this kernel tree.
