1	What:		/sys/class/leds/<led>/brightness
2	Date:		March 2006
3	KernelVersion:	2.6.17
4	Contact:	Richard Purdie <rpurdie@rpsys.net>
5	Description:
6			Set the brightness of the LED. Most LEDs don't
7			have hardware brightness support so will just be turned on for
8			non-zero brightness settings. The value is between 0 and
9			/sys/class/leds/<led>/max_brightness.

22	Description:
23			Set the trigger for this LED. A trigger is a kernel based source
24			of led events.
25			You can change triggers in a similar manner to the way an IO
26			scheduler is chosen. Trigger specific parameters can appear in
27			/sys/class/leds/<led> once a given trigger is selected.

31	KernelVersion:	2.6.38
32	Contact:	Richard Purdie <rpurdie@rpsys.net>
33	Description:
34			Invert the LED on/off state. This parameter is specific to
35			gpio and backlight triggers. In case of the backlight trigger,
36			it is useful when driving a LED which is intended to indicate
37			a device in a standby like state.
