6 bool "SPI support"
7 depends on HAS_IOMEM
8 help
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.
14
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.
20
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.

587 help
588 Qualcomm Universal Peripheral (QUP) core is an AHB slave that
589 provides a common data path (an output FIFO and an input FIFO)
590 for serial peripheral interface (SPI) mini-core. SPI in master
591 mode supports up to 50MHz, up to four chip selects, programmable
592 data path from 4 bits to 32 bits and numerous protocol variants.
593
594 This driver can also be built as a module. If so, the module
595 will be called spi_qup.
