tools/gpio: add the gpio-event-mon tool
The gpio-event-mon is used from userspace as an example of how to monitor GPIO line events. It will latch on to a certain GPIO line on a certain gpiochip and print timestamped events as they arrive. Example output: $ gpio-event-mon -n gpiochip2 -o 0 -r -f Monitoring line 0 on gpiochip2 Initial line value: 1 GPIO EVENT 946685798487609863: falling edge GPIO EVENT 946685798732482910: rising edge GPIO EVENT 946685799115997314: falling edge GPIO EVENT 946685799381469726: rising edge Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
