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.

16 Maximum brightness level for this led, default is 255 (LED_FULL).
18 What: /sys/class/leds/<led>/trigger
21 Contact: Richard Purdie <rpurdie@rpsys.net>
23 Set the trigger for this LED. A trigger is a kernel based source
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.
29 What: /sys/class/leds/<led>/inverted
32 Contact: Richard Purdie <rpurdie@rpsys.net>
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.
