This driver permits controlling local (on the system) gpios by using the libgpiod library. Support for gpiod v1 and v2 is added, and parses the options via the yaml parser. This can be tested with the gpio-sim module: https://docs.kernel.org/admin-guide/gpio/gpio-sim.html Signed-off-by: Neil Armstrong <neil.armstrong@linaro.org>
