Matt LaPlante692105b2009-01-26 11:12:25 +010057 These checks help ensure that GPIOs have been properly initialized
58 before they are used, and that sleeping calls are not made from

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.
