9 bool "SPI support"
10 depends on HAS_IOMEM
11 help
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.
17
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.
23
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.

200 This simple GPIO bitbanging SPI master uses the arch-neutral GPIO
201 interface to manage MOSI, MISO, SCK, and chipselect signals. SPI
202 slaves connected to a bus using this driver are configured as usual,
203 except that the spi_board_info.controller_data holds the GPIO number
204 for the chipselect used by this controller driver.
205
206 Note that this driver often won't achieve even 1 Mbit/sec speeds,
207 making it unusually slow for SPI. If your platform can inline
208 GPIO operations, you should be able to leverage that for better
209 speed with a custom version of this driver; see the source code.
