config LEDS_TRIGGER_ONESHOT
|
|
tristate "LED One-shot Trigger"
|
|
depends on LEDS_TRIGGERS
|
|
help
|
|
This allows LEDs to blink in one-shot pulses with parameters
|
|
controlled via sysfs. It's useful to notify the user on
|
|
sporadic events, when there are no clear begin and end trap points,
|
|
or on dense events, where this blinks the LED at constant rate if
|
|
rearmed continuously.
|
|
|
|
It also shows how to use the led_blink_set_oneshot() function.

config LEDS_TRIGGER_HEARTBEAT
|
|
tristate "LED Heartbeat Trigger"
|
|
depends on LEDS_TRIGGERS
|
|
help
|
|
This allows LEDs to be controlled by a CPU load average.
|
|
The flash frequency is a hyperbolic function of the 1-minute
|
|
load average.

config LEDS_TRIGGER_BACKLIGHT
|
|
tristate "LED backlight Trigger"
|
|
depends on LEDS_TRIGGERS
|
|
help
|
|
This allows LEDs to be controlled as a backlight device: they
|
|
turn off and on when the display is blanked and unblanked.
|
|
|
|
If unsure, say N.
|
|
|
|
config LEDS_TRIGGER_CPU
|
|
bool "LED CPU Trigger"
|
|
depends on LEDS_TRIGGERS
|
|
help
|
|
This allows LEDs to be controlled by active CPUs. This shows
|
|
the active CPUs across an array of LEDs so you can see which
|
|
CPUs are active on the system at any given moment.
|
|
|
|
If unsure, say N.

config LEDS_TRIGGER_GPIO
|

tristate "LED GPIO Trigger"
|
|
depends on LEDS_TRIGGERS
|
|
depends on GPIOLIB
|
|
help
|
|
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.

config LEDS_TRIGGER_DEFAULT_ON
|
|
tristate "LED Default ON Trigger"
|
|
depends on LEDS_TRIGGERS
|
|
help
|
|
This allows LEDs to be initialised in the ON state.
|
|
If unsure, say Y.
