+What: /sys/class/leds/<led>/gt683r/mode
+Date: Jun 2014
+KernelVersion: 3.17
+Contact: Janne Kanniainen <[email protected]>
+Description:
+ Set the mode of LEDs. You should notice that changing the mode
+ of one LED will update the mode of its two sibling devices as
+ well.
+
+ 0 - normal
+ 1 - audio
+ 2 - breathing
+
+ Normal: LEDs are fully on when enabled
+ Audio: LEDs brightness depends on sound level
+ Breathing: LEDs brightness varies at human breathing rate
