# SPI driver configuration

# 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
This selects a driver for the Broadcom BCM2835 SPI master.
The BCM2835 contains two types of SPI master controller; the
"universal SPI master", and the regular SPI controller. This driver
is for the regular SPI controller. Slave mode operation is not also
not supported.

This enables support for the High Speed SPI controller present on
newer Broadcom BCM63XX SoCs.
config SPI_BITBANG
tristate "Utilities for Bitbanging SPI masters"
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.
config SPI_BUTTERFLY
tristate "Parallel port adapter for AVR Butterfly (DEVELOPMENT)"
depends on PARPORT
select SPI_BITBANG

help
The external bus unit (EBU) found on the FALC-ON SoC has SPI
emulation that is designed for serial flash access. This driver
has only been tested with m25p80 type chips. The hardware has no
support for other types of SPI peripherals.
config SPI_GPIO
tristate "GPIO-based bitbanging SPI Master"
depends on GPIOLIB
select SPI_BITBANG
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.
Note that this driver often won't achieve even 1 Mbit/sec speeds,
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.
config SPI_IMG_SPFI
