7 title: GPIO controlled power off
10 - Sebastian Reichel <sre@kernel.org>
13 System power off support via a GPIO line. When a shutdown is
14 executed the operating system is expected to switch the GPIO
15 from inactive to active. After a delay (active-delay-ms) it
17 delay (inactive-delay-ms) it is configured as active again.

13 - ledtrig-gpio: drivers/leds/trigger/ledtrig-gpio.c will provide a LED trigger,
