4# NOTE:  the reason this doesn't show SPI slave support is mostly that
5# nobody's needed a slave side API yet.  The master-role API is not
6# fully appropriate there, so it'd need some thought to do well.

9	bool "SPI support"
10	depends on HAS_IOMEM
11	help
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.
