+         With a few GPIO pins, your system can bitbang the SPI protocol.
+         Select this to get SPI support through I/O pins (GPIO, parallel
+         port, etc).  Or, some systems' SPI master controller drivers use
+         this code to manage the per-word or per-transfer accesses to the
+         hardware shift registers.
+
+         This is library code, and is automatically selected by drivers that
+         need it.  You only need to select this explicitly to support driver
+         modules that aren't part of this kernel tree.
