6	bool
7	help
8	  Selecting this config option from the architecture Kconfig allows

17	  it is possible to use gpiolib on the architecture, but let the
18	  user decide whether to actually build it or not.
19	  Select this instead of ARCH_REQUIRE_GPIOLIB, if your architecture does
20	  not depend on GPIOs being available, but rather let the user
21	  decide whether he needs it or not.

67	  These checks help ensure that GPIOs have been properly initialized
68	  before they are used, and that sleeping calls are not made from
69	  non-sleeping contexts.  They can make bitbanged serial protocols
70	  slower.  The diagnostics help catch the type of setup errors

77	  Say Y here to add a sysfs interface for GPIOs.
78
79	  This is mostly useful to work around omissions in a system's
80	  kernel support.  Those are common in custom and semicustom
81	  hardware assembled using standard kernels with a minimum of
82	  custom patches.  In those cases, userspace code may import
83	  a given GPIO from the kernel, if no kernel driver requested it.
84
85	  Kernel drivers may also request that a particular GPIO be
86	  exported to userspace; this can be useful when debugging.
