Matt LaPlante692105b2009-01-26 11:12:25 +010063 These checks help ensure that GPIOs have been properly initialized
64 before they are used, and that sleeping calls are not made from
65 non-sleeping contexts. They can make bitbanged serial protocols
David Brownella9c5fff2008-02-04 22:28:17 -080066 slower. The diagnostics help catch the type of setup errors

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.

723 Say yes here to access the GPIO signals of Nano River
724 Technologies Viperboard. There are two GPIO chips on the
725 board: gpioa and gpiob.
726 See viperboard API specification and Nano
727 River Tech's viperboard.h for detailed meaning
728 of the module parameters.
