Description: Utilities for Bitbanging SPI masters
More info: 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.
