1# 2# SPI driver configuration 3# 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. 7# 8menuconfig SPI 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. 28 29if SPI 30 31config SPI_DEBUG 32 boolean "Debug support for SPI drivers" 33 depends on DEBUG_KERNEL 34 help 35 Say "yes" to enable debug messaging (like dev_dbg and pr_debug), 36 sysfs, and debugfs support in SPI controller and protocol drivers. 37 38# 39# MASTER side ... talking to discrete SPI slave chips including microcontrollers 40# 41 42config SPI_MASTER 43# boolean "SPI Master Support" 44 boolean 45 default SPI 46 help 47 If your system has an master-capable SPI controller (which 48 provides the clock and chipselect), you can enable that 49 controller and the protocol drivers for the SPI slave chips 50 that are connected. 51 52if SPI_MASTER 53 54comment "SPI Master Controller Drivers" 55 56config SPI_ALTERA 57 tristate "Altera SPI Controller" 58 select SPI_BITBANG 59 help 60 This is the driver for the Altera SPI Controller. 61 62config SPI_ATH79 63 tristate "Atheros AR71XX/AR724X/AR913X SPI controller driver" 64 depends on ATH79 && GPIOLIB 65 select SPI_BITBANG 66 help 67 This enables support for the SPI controller present on the 68 Atheros AR71XX/AR724X/AR913X SoCs. 69 70config SPI_ATMEL 71 tristate "Atmel SPI Controller" 72 depends on (ARCH_AT91 || AVR32 || COMPILE_TEST) 73 help 74 This selects a driver for the Atmel SPI Controller, present on 75 many AT32 (AVR32) and AT91 (ARM) chips. 76 77config SPI_BCM2835 78 tristate "BCM2835 SPI controller" 79 depends on ARCH_BCM2835 || COMPILE_TEST 80 help 81 This selects a driver for the Broadcom BCM2835 SPI master. 82 83 The BCM2835 contains two types of SPI master controller; the 84 "universal SPI master", and the regular SPI controller.
