This patch converts the IDE specific LED trigger to a generic disk activity LED trigger. The libata core is now a trigger source just like before the IDE disk driver. It's merely a replacement of the string ide by disk. The patch is taken from http://dev.gentoo.org/~josejx/ata.patch and is widely used by any ibook/powerbook owners with great satisfaction. Likewise, it is very often used successfully on different ARM platforms. Unlike the original patch, the existing 'ide-disk' trigger is still available for backward compatibility. That reduce the amount of patches in affected device trees out of the mainline kernel. For further development, the new name 'disk-activity' should be used.

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.

tristate "LED Timer Trigger"
|

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
|

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.

|
|
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.

If unsure, say N.

bool "LED Panic Trigger"
|

depends on LEDS_TRIGGERS
|
|
help
|
|
This allows LEDs to be configured to blink on a kernel panic.
|
|
Enabling this option will allow to mark certain LEDs as panic indicators,
|
|
allowing to blink them on a kernel panic, even if they are set to
|
|
a different trigger.
