 414        help
 415          This allows LEDs to be controlled by a CPU load average.
 416          The flash frequency is a hyperbolic function of the 1-minute
 417          load average.

 424          This allows LEDs to be controlled as a backlight device: they
 425          turn off and on when the display is blanked and unblanked.

 433        help
 434          This allows LEDs to be controlled by gpio events. It's good
 435          when using gpios as switches and triggering the needed LEDs
 436          from there. One use case is n810's keypad LEDs that could
 437          be triggered by this trigger when user slides up to show
 438          keypad.

 446          This allows LEDs to be initialised in the ON state.
