Say Y here to add some extra checks and diagnostics to GPIO calls.

These checks help ensure that GPIOs have been properly initialized
|
|
before they are used, and that sleeping calls are not made from
|
|
non-sleeping contexts. They can make bitbanged serial protocols

slower. The diagnostics help catch the type of setup errors

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.
