  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
  18           SPI is widely used by microcontrollers to talk with sensors,
  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.
