Selecting this config option from the architecture Kconfig allows
the architecture to provide a custom asm/gpio.h implementation
overriding the default implementations. New uses of this are
strongly discouraged.
config ARCH_WANT_OPTIONAL_GPIOLIB

help
Select this config option from the architecture Kconfig, if
it is possible to use gpiolib on the architecture, but let the
user decide whether to actually build it or not.
Select this instead of ARCH_REQUIRE_GPIOLIB, if your architecture does
not depend on GPIOs being available, but rather let the user
decide whether he needs it or not.

Say Y here to add some extra checks and diagnostics to GPIO calls.
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.

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

Say yes here to provide access to most "quasi-bidirectional" I2C
GPIO expanders used for additional digital outputs or inputs.
Most of these parts are from NXP, though TI is a second source for

16 bits: pcf8575, pcf8575c, pca8575,
pca9671, pca9673, pca9675
Your board setup code will need to declare the expanders in
use, and assign numbers to the GPIOs they expose. Those GPIOs
can then be used from drivers and other kernel code, just like
other GPIOs, but only accessible from task contexts.
This driver provides an in-kernel interface to those GPIOs using
platform-neutral GPIO calls.
