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