The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate.

bool "LED Trigger support"

depends on LEDS_CLASS
|
|
help
|
|
This option enables trigger support for the leds class.
|
|
These triggers allow kernel events to drive the LEDs and can
|
|
be configured via sysfs. If unsure, say Y.

depends on LEDS_TRIGGERS
|
|
help
|
|
This allows LEDs to be controlled by a programmable timer
|
|
via sysfs. Some LED hardware can be programmed to start
|
|
blinking the LED without any further software interaction.
|
|
For more details read Documentation/leds/leds-class.txt.

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.

help
|

The flash frequency is a hyperbolic function of the 1-minute
|

turn off and on when the display is blanked and unblanked.

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.

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.
