  69           non-sleeping contexts.  They can make bitbanged serial protocols

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

  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.
