In linux kernel since version 3.10 (release Date: 2013-06-30)
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.
