# SPI driver configuration

# NOTE: the reason this doesn't show SPI slave support is mostly that
# nobody's needed a slave side API yet. The master-role API is not
# fully appropriate there, so it'd need some thought to do well.

menuconfig SPI
bool "SPI support"
depends on HAS_IOMEM
help
The "Serial Peripheral Interface" is a low level synchronous
protocol. Chips that support SPI can have data transfer rates
up to several tens of Mbit/sec. Chips are addressed with a
controller and a chipselect. Most SPI slaves don't support
dynamic device discovery; some are even write-only or read-only.
SPI is widely used by microcontrollers to talk with sensors,
eeprom and flash memory, codecs and various other controller
chips, analog to digital (and d-to-a) converters, and more.
MMC and SD cards can be accessed using SPI protocol; and for
DataFlash cards used in MMC sockets, SPI must always be used.
SPI is one of a family of similar protocols using a four wire
interface (select, clock, data in, data out) including Microwire
(half duplex), SSP, SSI, and PSP. This driver framework should
work with most such devices and controllers.

help
If your system has an master-capable SPI controller (which
provides the clock and chipselect), you can enable that
controller and the protocol drivers for the SPI slave chips
that are connected.

help
With a few GPIO pins, your system can bitbang the SPI protocol.
Select this to get SPI support through I/O pins (GPIO, parallel
port, etc). Or, some systems' SPI master controller drivers use
this code to manage the per-word or per-transfer accesses to the
hardware shift registers.
This is library code, and is automatically selected by drivers that
need it. You only need to select this explicitly to support driver
modules that aren't part of this kernel tree.

help
This simple GPIO bitbanging SPI master uses the arch-neutral GPIO
interface to manage MOSI, MISO, SCK, and chipselect signals. SPI
slaves connected to a bus using this driver are configured as usual,
except that the spi_board_info.controller_data holds the GPIO number
for the chipselect used by this controller driver.

making it unusually slow for SPI. If your platform can inline
GPIO operations, you should be able to leverage that for better
speed with a custom version of this driver; see the source code.
