45 non-sleeping contexts. They can make bitbanged serial protocols

55 This is mostly useful to work around omissions in a system's
56 kernel support. Those are common in custom and semicustom
57 hardware assembled using standard kernels with a minimum of
58 custom patches. In those cases, userspace code may import
59 a given GPIO from the kernel, if no kernel driver requested it.
60
61 Kernel drivers may also request that a particular GPIO be
62 exported to userspace; this can be useful when debugging.
