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.

486 This option enables support for N GPIOs found on Avionic Design
487 I2C GPIO expanders. The register space will be extended by powers
488 of two, so the controller will need to accomodate for that. For
489 example: if a controller provides 48 pins, 6 registers will be
490 enough to represent all pins, but the driver will assume a
491 register layout for 64 pins (8 registers).

509 The BT8xx frame grabber chip has 24 GPIO pins than can be abused
510 as a cheap PCI GPIO card.

512 This chip can be found on Miro, Hauppauge and STB TV-cards.

514 The card needs to be physically altered for using it as a
