1# 2# SPI driver configuration 3# 4menuconfig SPI 5 bool "SPI support" 6 depends on HAS_IOMEM 7 help 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.
