| 59 | hardware assembled using standard kernels with a minimum of |
| 60 | custom patches. In those cases, userspace code may import |
| 61 | a given GPIO from the kernel, if no kernel driver requested it. |
| 62 | |
| 63 | Kernel drivers may also request that a particular GPIO be |
| 64 | exported to userspace; this can be useful when debugging. |
