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

  80           This is mostly useful to work around omissions in a system's

  82           hardware assembled using standard kernels with a minimum of
  83           custom patches.  In those cases, userspace code may import
  84           a given GPIO from the kernel, if no kernel driver requested it.
  85
  86           Kernel drivers may also request that a particular GPIO be
  87           exported to userspace; this can be useful when debugging.
