7 title: GPIO controlled reset
10 - Sebastian Reichel <sre@kernel.org>
13 Drive a GPIO line that can be used to restart the system from a restart handler.
16 request the given gpio line and install a restart handler. If the optional properties
17 'open-source' is not found, the GPIO line will be driven in the inactive state. Otherwise its
18 not driven until the restart is initiated.

H A Ddrivers-on-gpio.rst2 Subsystem drivers using GPIO
5 Note that standard kernel drivers exist for common GPIO tasks and will provide
6 the right in-kernel and userspace APIs/ABIs for the job, and that these
10 - leds-gpio: drivers/leds/leds-gpio.c will handle LEDs connected to GPIO
13 - ledtrig-gpio: drivers/leds/trigger/ledtrig-gpio.c will provide a LED trigger,
14 i.e. a LED will turn on/off in response to a GPIO line going high or low
15 (and that LED may in turn use the leds-gpio as per above).
17 - gpio-keys: drivers/input/keyboard/gpio_keys.c is used when your GPIO line
20 - gpio-keys-polled: drivers/input/keyboard/gpio_keys_polled.c is used when your
21 GPIO line cannot generate interrupts, so it needs to be periodically polled
