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.
17
3cb2fccc 18 SPI is widely used by microcontrollers to talk with sensors,
8ae12a0d
DB
19 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.

230 slaves connected to a bus using this driver are configured as usual,

463 Enable FIQ support for the S3C24XX SPI driver to provide pseudo
464 DMA by using the fast-interrupt request framework, This allows
465 the driver to get DMA-like performance when there are either
466 no free DMA channels, or when doing transfers that required both
467 TX and RX data paths.
