+description:
+   GENI based Qualcomm Technologies Inc Universal Peripheral version 5 (QUPv3)
+   Serial Peripheral Interface (SPI)
+   The QUP v3 core is a GENI based 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.
