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

91 This driver can also be built as a module. If so, the module
92 will be called au1550_spi.
95 tristate "Utilities for Bitbanging SPI masters"
97 With a few GPIO pins, your system can bitbang the SPI protocol.
98 Select this to get SPI support through I/O pins (GPIO, parallel
99 port, etc). Or, some systems' SPI master controller drivers use
100 this code to manage the per-word or per-transfer accesses to the
101 hardware shift registers.
103 This is library code, and is automatically selected by drivers that
104 need it. You only need to select this explicitly to support driver
105 modules that aren't part of this kernel tree.

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