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. | |
