CONFIG_LEDS_TRIGGER_GPIO: LED GPIO Trigger

General informations

The Linux kernel configuration item CONFIG_LEDS_TRIGGER_GPIO has multiple definitions:

LED GPIO Trigger found in drivers/leds/trigger/Kconfig

The configuration item CONFIG_LEDS_TRIGGER_GPIO:

• prompt: LED GPIO Trigger
• type: tristate
• depends on: CONFIG_GPIOLIB || CONFIG_COMPILE_TEST
• defined in drivers/leds/trigger/Kconfig
• found in Linux kernels: 3.10–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.13
• modules built: ledtrig-gpio, ledtrig-gpio

Help text

This allows LEDs to be controlled by gpio events. It's good when using gpios as switches and triggering the needed LEDs from there. Triggers are defined as device properties.

If unsure, say N.

LED GPIO Trigger found in drivers/leds/Kconfig

The configuration item CONFIG_LEDS_TRIGGER_GPIO:

• prompt: LED GPIO Trigger
• type: tristate
• depends on: ( CONFIG_LEDS_TRIGGERS ) && ( CONFIG_GPIOLIB )
• defined in drivers/leds/Kconfig
• found in Linux kernels: 2.6.30–2.6.39, 3.0–3.9
• modules built: ledtrig-gpio, ledtrig-gpio

Help text

This allows LEDs to be controlled by gpio events. It's good when using gpios as switches and triggering the needed LEDs from there. One use case is n810's keypad LEDs that could be triggered by this trigger when user slides up to show keypad.

If unsure, say N.
