This enables GPIO support through the generic GPIO library.
You only need to enable this, if you also want to enable
- one or more of the GPIO expansion card drivers below.
+ one or more of the GPIO drivers below.
If unsure, say N.
Kernel drivers may also request that a particular GPIO be
exported to userspace; this can be useful when debugging.
