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

75 This is mostly useful to work around omissions in a system's
76 kernel support. Those are common in custom and semicustom
77 hardware assembled using standard kernels with a minimum of
78 custom patches. In those cases, userspace code may import
79 a given GPIO from the kernel, if no kernel driver requested it.
80
81 Kernel drivers may also request that a particular GPIO be
82 exported to userspace; this can be useful when debugging.

503 Your board setup code will need to declare the expanders in
504 use, and assign numbers to the GPIOs they expose. Those GPIOs
505 can then be used from drivers and other kernel code, just like
506 other GPIOs, but only accessible from task contexts.
507
508 This driver provides an in-kernel interface to those GPIOs using
509 platform-neutral GPIO calls.
