2 # SPI driver configuration
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.
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.
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.

39 # bool "SPI Master Support"
43 If your system has an master-capable SPI controller (which
