# 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.

# 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

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.

depends on GENERIC_GPIO

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.
