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

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

1169           The BT8xx frame grabber chip has 24 GPIO pins that can be abused
1170           as a cheap PCI GPIO card.
1171
1172           This chip can be found on Miro, Hauppauge and STB TV-cards.
1173
1174           The card needs to be physically altered for using it as a
1175           GPIO card. For more information on how to build a GPIO card
1176           from a BT8xx TV card, see the documentation file at
1177           Documentation/bt8xxgpio.txt

1179           If unsure, say N.
