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

57 tristate "Atmel SPI Controller"
58 depends on (ARCH_AT91 || AVR32)
60 This selects a driver for the Atmel SPI Controller, present on
61 many AT32 (AVR32) and AT91 (ARM) chips.
64 tristate "SPI controller driver for ADI Blackfin5xx"
67 This is the SPI controller master driver for Blackfin 5xx processor.
70 tristate "Au1550/Au12x0 SPI Controller"
71 depends on (SOC_AU1550 || SOC_AU1200) && EXPERIMENTAL
74 If you say yes to this option, support will be included for the
75 Au1550 SPI controller (may also work with Au1200,Au1210,Au1250).
77 This driver can also be built as a module. If so, the module
78 will be called au1550_spi.
81 tristate "Bitbanging SPI master"
83 With a few GPIO pins, your system can bitbang the SPI protocol.
84 Select this to get SPI support through I/O pins (GPIO, parallel
85 port, etc). Or, some systems' SPI master controller drivers use
86 this code to manage the per-word or per-transfer accesses to the
87 hardware shift registers.
89 This is library code, and is automatically selected by drivers that
90 need it. You only need to select this explicitly to support driver
91 modules that aren't part of this kernel tree.

215 comment "SPI Protocol Masters"
218 tristate "SPI EEPROMs from most vendors"
221 Enable this driver to get read/write support to most SPI EEPROMs,
222 after you configure the board init code to know about each eeprom
223 on your target board.
225 This driver can also be built as a module. If so, the module
229 depends on SPI_MASTER
230 tristate "TSC2101 chip support"
232 Say Y here if you want support for the TSC2101 chip.
233 At the moment it provides basic register read / write interface
234 as well as a way to enable the MCLK clock.
237 depends on SPI_MASTER
238 tristate "TSC2102 codec support"
240 Say Y here if you want support for the TSC2102 chip. It
241 will be needed for the touchscreen driver on some boards.
244 depends on SPI_MASTER && EXPERIMENTAL
245 tristate "TI TSC210x (TSC2101/TSC2102) support"
247 Say Y here if you want support for the TSC210x chips. Some
248 boards use these for touchscreen and audio support.
250 These are members of a family of highly integrated PDA analog
251 interface circuit. They include a 12-bit ADC used for battery,
252 temperature, touchscreen, and other sensors. They also have
253 an audio DAC and amplifier, and in some models an audio ADC.
254 The audio support is highly chip-specific, but most of the
255 sensor support works the same.
257 Note that the device has to be present in the board's SPI
258 devices table for this driver to load. This driver doesn't
259 automatically enable touchscreen, sensors or audio
260 functionality - enable these in their respective menus.

271 converter (ADC) including drivers, touch pressure measurement
272 capability, keypad controller, and 8-bit D/A converter (DAC) output
273 for LCD contrast control.
275 To compile this driver as a module, choose M here: the
276 module will be called tsc2301.
