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

If your system has an master-capable SPI controller (which

provides the clock and chipselect), you can enable that
|
|
controller and the protocol drivers for the SPI slave chips

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