2 Subsystem drivers using GPIO5 Note that standard kernel drivers exist for common GPIO tasks and will provide6 the right in-kernel and userspace APIs/ABIs for the job, and that these10 - leds-gpio: drivers/leds/leds-gpio.c will handle LEDs connected to GPIO13 - 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 low15 (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 line20 - gpio-keys-polled: drivers/input/keyboard/gpio_keys_polled.c is used when your21 GPIO line cannot generate interrupts, so it needs to be periodically polled[all …]
