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

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