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. This driver framework should 23 work with most such devices and controllers. 24 25if SPI 26 27config SPI_DEBUG 28 bool "Debug support for SPI drivers" 29 depends on DEBUG_KERNEL 30 help 31 Say "yes" to enable debug messaging (like dev_dbg and pr_debug), 32 sysfs, and debugfs support in SPI controller and protocol drivers. 33 34# 35# MASTER side ... talking to discrete SPI slave chips including microcontrollers 36# 37 38config SPI_MASTER 39# bool "SPI Master Support" 40 bool 41 default SPI 42 help 43 If your system has an master-capable SPI controller (which 44 provides the clock and chipselect), you can enable that 45 controller and the protocol drivers for the SPI slave chips 46 that are connected. 47 48if SPI_MASTER 49 50config SPI_MEM 51 bool "SPI memory extension" 52 help 53 Enable this option if you want to enable the SPI memory extension. 54 This extension is meant to simplify interaction with SPI memories 55 by providing a high-level interface to send memory-like commands. 56 57comment "SPI Master Controller Drivers" 58 59config SPI_ALTERA 60 tristate "Altera SPI Controller" 61 help 62 This is the driver for the Altera SPI Controller. 63 64config SPI_ATH79 65 tristate "Atheros AR71XX/AR724X/AR913X SPI controller driver" 66 depends on ATH79 && GPIOLIB 67 select SPI_BITBANG 68 help 69 This enables support for the SPI controller present on the 70 Atheros AR71XX/AR724X/AR913X SoCs. 71 72config SPI_ARMADA_3700 73 tristate "Marvell Armada 3700 SPI Controller" 74 depends on (ARCH_MVEBU && OF) || COMPILE_TEST 75 help 76 This enables support for the SPI controller present on the 77 Marvell Armada 3700 SoCs. 78 79config SPI_ATMEL 80 tristate "Atmel SPI Controller" 81 depends on ARCH_AT91 || COMPILE_TEST 82 help 83 This selects a driver for the Atmel SPI Controller, present on 84 many AT91 ARM chips. 85 86config SPI_AU1550 87 tristate "Au1550/Au1200/Au1300 SPI Controller" 88 depends on MIPS_ALCHEMY 89 select SPI_BITBANG 90 help 91 If you say yes to this option, support will be included for the 92 PSC SPI controller found on Au1550, Au1200 and Au1300 series. 93 94config SPI_AXI_SPI_ENGINE 95 tristate "Analog Devices AXI SPI Engine controller" 96 depends on HAS_IOMEM 97 help 98 This enables support for the Analog Devices AXI SPI Engine SPI controller. 99 It is part of the SPI Engine framework that is used in some Analog Devices 100 reference designs for FPGAs. 101 102config SPI_BCM2835 103 tristate "BCM2835 SPI controller" 104 depends on GPIOLIB 105 depends on ARCH_BCM2835 || COMPILE_TEST 106 help 107 This selects a driver for the Broadcom BCM2835 SPI master. 108 109 The BCM2835 contains two types of SPI master controller; the 110 "universal SPI master", and the regular SPI controller.
