 395 config LEDS_TRIGGER_TIMER
 396         tristate "LED Timer Trigger"
 397         depends on LEDS_TRIGGERS
 398         help
 399           This allows LEDs to be controlled by a programmable timer
 400           via sysfs. Some LED hardware can be programmed to start
 401           blinking the LED without any further software interaction.
 402           For more details read Documentation/leds-class.txt.

 408         depends on IDE_GD_ATA
 409         depends on LEDS_TRIGGERS
 410         help
 411           This allows LEDs to be controlled by IDE disk activity.

 414 config LEDS_TRIGGER_HEARTBEAT
 415         tristate "LED Heartbeat Trigger"
 416         depends on LEDS_TRIGGERS
 417         help
 418           This allows LEDs to be controlled by a CPU load average.
 419           The flash frequency is a hyperbolic function of the 1-minute
 420           load average.
 421           If unsure, say Y.

 423 config LEDS_TRIGGER_BACKLIGHT
 424         tristate "LED backlight Trigger"
 425         depends on LEDS_TRIGGERS
 426         help
 427           This allows LEDs to be controlled as a backlight device: they
 428           turn off and on when the display is blanked and unblanked.

 433         tristate "LED GPIO Trigger"

 435         depends on GPIOLIB
 436         help
 437           This allows LEDs to be controlled by gpio events. It's good
 438           when using gpios as switches and triggering the needed LEDs
 439           from there. One use case is n810's keypad LEDs that could
 440           be triggered by this trigger when user slides up to show
 441           keypad.

 447         depends on LEDS_TRIGGERS
 448         help
 449           This allows LEDs to be initialised in the ON state.
 450           If unsure, say Y.
