 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.

443           provides a common data path (an output FIFO and an input FIFO)
444           for serial peripheral interface (SPI) mini-core. SPI in master
