  43           These checks help ensure that GPIOs have been properly initialized
  44           before they are used, and that sleeping calls are not made from
  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.

 789           Your board setup code will need to declare the expanders in
 790           use, and assign numbers to the GPIOs they expose.  Those GPIOs
 791           can then be used from drivers and other kernel code, just like
 792           other GPIOs, but only accessible from task contexts.
 793
 794           This driver provides an in-kernel interface to those GPIOs using
 795           platform-neutral GPIO calls.
