Code blocks are indented with two spaces. If there's a leading TAB, the
syntax highlighting might be broken in some editors. To prevent that,
unify all code blocks by using spaces instead of leading TAB(s).

Consistently use active/inactive to describe logical line values, rather
than high/low, which is used for physical values, or asserted/de-asserted
which is awkward.

Optional GPIOLIB as in not depended on or selected by a driver
should NOT use any *_optional() calls, this becomes paradoxical.

The true Hi-Z (a.k.a. high impedance) mode is when pin is completely
disconnected from the chip. This includes input buffer as well.
Nevertheless, some hardware may not support that mode and they are
considering input only as Hi-Z, but more precisely it is an equivalent
to that, in electronics it's basically "an antenna mode".

Sligthly correct documentation to take the above into consideration.

There are only a handful of users of gpio_export() and
related functions.

As these are just wrappers around the modern gpiod_export()
helper, remove the wrappers and open-code the gpio_to_desc
in all callers to shrink the legacy API.

gpio_set_debounce() only has a single user, which is trivially
