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

  59           This is mostly useful to work around omissions in a system's
  60           kernel support.  Those are common in custom and semicustom
  61           hardware assembled using standard kernels with a minimum of
  62           custom patches.  In those cases, userspace code may import
  63           a given GPIO from the kernel, if no kernel driver requested it.
  64
  65           Kernel drivers may also request that a particular GPIO be
  66           exported to userspace; this can be useful when debugging.
