+ 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
that are most common when setting up new platforms or boards.
Kernel drivers may also request that a particular GPIO be
exported to userspace; this can be useful when debugging.
