5Description:
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.

22Description:
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.

33Description:
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.
