   8           The "Serial Peripheral Interface" is a low level synchronous
   9           protocol.  Chips that support SPI can have data transfer rates
  10           up to several tens of Mbit/sec.  Chips are addressed with a
  11           controller and a chipselect.  Most SPI slaves don't support
  12           dynamic device discovery; some are even write-only or read-only.
  13
  14           SPI is widely used by microcontrollers to talk with sensors,
  15           eeprom and flash memory, codecs and various other controller
  16           chips, analog to digital (and d-to-a) converters, and more.
  17           MMC and SD cards can be accessed using SPI protocol; and for
  18           DataFlash cards used in MMC sockets, SPI must always be used.
  19
  20           SPI is one of a family of similar protocols using a four wire
  21           interface (select, clock, data in, data out) including Microwire
  22           (half duplex), SSP, SSI, and PSP.  This driver framework should
  23           work with most such devices and controllers.
