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

1009 Say yes here to access the GPIO signals of Nano River
1010 Technologies Viperboard. There are two GPIO chips on the
1011 board: gpioa and gpiob.
1012 See viperboard API specification and Nano
1013 River Tech's viperboard.h for detailed meaning
1014 of the module parameters.
