  58          before they are used, and that sleeping calls are not made from
  59          non-sleeping contexts.  They can make bitbanged serial protocols

  69          This is mostly useful to work around omissions in a system's
  70          kernel support.  Those are common in custom and semicustom
  71          hardware assembled using standard kernels with a minimum of
  72          custom patches.  In those cases, userspace code may import
  73          a given GPIO from the kernel, if no kernel driver requested it.
  74
  75          Kernel drivers may also request that a particular GPIO be
  76          exported to userspace; this can be useful when debugging.
