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

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