2 # 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.
39 # 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
