  67           These checks help ensure that GPIOs have been properly initialized
  68           before they are used, and that sleeping calls are not made from
  69           non-sleeping contexts.  They can make bitbanged serial protocols

  79           This is mostly useful to work around omissions in a system's
  80           kernel support.  Those are common in custom and semicustom
  81           hardware assembled using standard kernels with a minimum of
  82           custom patches.  In those cases, userspace code may import
  83           a given GPIO from the kernel, if no kernel driver requested it.
  84
  85           Kernel drivers may also request that a particular GPIO be
  86           exported to userspace; this can be useful when debugging.
