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

				46	If your system has an master-capable SPI controller (which
				47	provides the clock and chipselect), you can enable that
				48	controller and the protocol drivers for the SPI slave chips
				49	that are connected.

				56	depends on SPI_MASTER && EXPERIMENTAL
				57	help
				58	With a few GPIO pins, your system can bitbang the SPI protocol.
				59	Select this to get SPI support through I/O pins (GPIO, parallel
				60	port, etc). Or, some systems' SPI master controller drivers use
				61	this code to manage the per-word or per-transfer accesses to the
				62	hardware shift registers.
				63
				64	This is library code, and is automatically selected by drivers that
				65	need it. You only need to select this explicitly to support driver
				66	modules that aren't part of this kernel tree.

				76	This same cable can be used to flash new firmware.

				85
				86	Note, this driver uniquely supports the SPI controller on the MPC83xx
				87	family of PowerPC processors. The MPC83xx uses a simple set of shift
				88	registers for data (opposed to the CPM based descriptor model).
