This is mostly useful to work around omissions in a system's |
|
kernel support. Those are common in custom and semicustom |
|
hardware assembled using standard kernels with a minimum of |
|
custom patches. In those cases, userspace code may import |
|
a given GPIO from the kernel, if no kernel driver requested it. |
|
|
|
Kernel drivers may also request that a particular GPIO be |
|
exported to userspace; this can be useful when debugging. |
