Chips that support SPI can have data transfer rates up to several tens of Mbit/sec. Chips are addressed with a controller and a chipselect. Most SPI slaves don't support dynamic device discovery; some are even write-only or read-only. SPI is widely used by microcontrollers to talk with sensors, eeprom and flash memory, codecs and various other controller chips, analog to digital (and d-to-a) converters, and more. MMC and SD cards can be accessed using SPI protocol; and for DataFlash cards used in MMC sockets, SPI must always be used. SPI is one of a family of similar protocols using a four wire interface (select, clock, data in, data out) including Microwire (half duplex), SSP, SSI, and PSP. This driver framework should work with most such devices and controllers. if SPI config SPI_DEBUG bool "Debug support for SPI drivers" depends on DEBUG_KERNEL help Say "yes" to enable debug messaging (like dev_dbg and pr_debug), sysfs, and debugfs support in SPI controller and protocol drivers. # # MASTER side ... talking to discrete SPI slave chips including microcontrollers # config SPI_MASTER # bool "SPI Master Support" bool default SPI help If your system has an master-capable SPI controller (which provides the clock and chipselect), you can enable that controller and the protocol drivers for the SPI slave chips that are connected. if SPI_MASTER config SPI_MEM bool "SPI memory extension" help Enable this option if you want to enable the SPI memory extension.
