   6           This is an SPI driver to register 1 to 4 custom SPI buses using
   7           GPIO lines. Each bus can have up to 8 slaves.
   8           The devices will be exposed to userspace as /dev/spidevX.X

  10           This module is maily intended to interface microcontrollers
  11           and other SPI devices without a specific kernel driver.

  13           This support is also available as a module.  If so, the module
  14           will be called spi-gpio-custom.
