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

KernelVersion: 2.6.38

Invert the LED on/off state. This parameter is specific to
gpio and backlight triggers. In case of the backlight trigger,
it is useful when driving a LED which is intended to indicate
a device in a standby like state.
