 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.

830           Say yes here to access the GPIO signals of Nano River
831           Technologies Viperboard. There are two GPIO chips on the
832           board: gpioa and gpiob.
833           See viperboard API specification and Nano
834           River Tech's viperboard.h for detailed meaning
835           of the module parameters.
