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,

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

154 slaves connected to a bus using this driver are configured as usual,
155 except that the spi_board_info.controller_data holds the GPIO number

158 Note that this driver often won't achieve even 1 Mbit/sec speeds,
159 making it unusually slow for SPI. If your platform can inline
160 GPIO operations, you should be able to leverage that for better
161 speed with a custom version of this driver; see the source code.
