2 # SPI driver configuration
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.
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.
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.
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.
32 boolean "Debug support for SPI drivers"
33 depends on DEBUG_KERNEL
35 Say "yes" to enable debug messaging (like dev_dbg and pr_debug),
36 sysfs, and debugfs support in SPI controller and protocol drivers.
39 # MASTER side ... talking to discrete SPI slave chips including microcontrollers
43 # boolean "SPI Master Support"
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

98 tristate "Utilities for Bitbanging SPI masters"
100 With a few GPIO pins, your system can bitbang the SPI protocol.
101 Select this to get SPI support through I/O pins (GPIO, parallel
102 port, etc). Or, some systems' SPI master controller drivers use
103 this code to manage the per-word or per-transfer accesses to the
104 hardware shift registers.
106 This is library code, and is automatically selected by drivers that
107 need it. You only need to select this explicitly to support driver
108 modules that aren't part of this kernel tree.
111 tristate "Parallel port adapter for AVR Butterfly (DEVELOPMENT)"

116 Butterfly <http://www.atmel.com/products/avr/butterfly>, an

142 tristate "GPIO-based bitbanging SPI Master"
143 depends on GENERIC_GPIO
146 This simple GPIO bitbanging SPI master uses the arch-neutral GPIO
147 interface to manage MOSI, MISO, SCK, and chipselect signals. SPI
148 slaves connected to a bus using this driver are configured as usual,
149 except that the spi_board_info.controller_data holds the GPIO number
150 for the chipselect used by this controller driver.
152 Note that this driver often won't achieve even 1 Mbit/sec speeds,
153 making it unusually slow for SPI. If your platform can inline
154 GPIO operations, you should be able to leverage that for better
155 speed with a custom version of this driver; see the source code.
