# # SPI driver configuration # # NOTE: the reason this doesn't show SPI slave support is mostly that # nobody's needed a slave side API yet. The master-role API is not # fully appropriate there, so it'd need some thought to do well. # menuconfig SPI bool "SPI support" depends on HAS_IOMEM help The "Serial Peripheral Interface" is a low level synchronous protocol. 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 comment "SPI Master Controller Drivers" config SPI_ALTERA tristate "Altera SPI Controller" select SPI_BITBANG help This is the driver for the Altera SPI Controller. config SPI_ATH79 tristate "Atheros AR71XX/AR724X/AR913X SPI controller driver" depends on ATH79 && GPIOLIB select SPI_BITBANG help This enables support for the SPI controller present on the Atheros AR71XX/AR724X/AR913X SoCs. config SPI_ATMEL tristate "Atmel SPI Controller" depends on HAS_DMA depends on (ARCH_AT91 || AVR32 || COMPILE_TEST) help This selects a driver for the Atmel SPI Controller, present on many AT32 (AVR32) and AT91 (ARM) chips. config SPI_AU1550 tristate "Au1550/Au1200/Au1300 SPI Controller" depends on MIPS_ALCHEMY select SPI_BITBANG help If you say yes to this option, support will be included for the PSC SPI controller found on Au1550, Au1200 and Au1300 series. config SPI_AXI_SPI_ENGINE tristate "Analog Devices AXI SPI Engine controller" depends on HAS_IOMEM help This enables support for the Analog Devices AXI SPI Engine SPI controller.
