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

40 # bool "SPI Master Support"
44 If your system has an master-capable SPI controller (which
45 provides the clock and chipselect), you can enable that
46 controller and the protocol drivers for the SPI slave chips
52 bool "SPI memory extension"
54 Enable this option if you want to enable the SPI memory extension.
55 This extension is meant to simplify interaction with SPI memories
56 by providing a high-level interface to send memory-like commands.
