+What: /sys/class/leds/<led>/gt683r/mode
+Date: Jun 2014
+KernelVersion: 3.17
+Contact: Janne Kanniainen <janne.kanniainen@gmail.com>
+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

LEDs connected to pca9632, pca9633 or pca9634
Required properties:
-- compatible : should be : "nxp,pca9632", "nxp,pca9633" or "nxp,pca9634"
+- compatible : should be : "nxp,pca9632", "nxp,pca9633", "nxp,pca9634" or "nxp,pca9635"
Optional properties:
-- nxp,totem-pole : use totem pole (push-pull) instead of default open-drain
+- nxp,totem-pole : use totem pole (push-pull) instead of open-drain (pca9632 defaults
+ to open-drain, newer chips to totem pole)
- nxp,hw-blink : use hardware blinking instead of software blinking
Each led is represented as a sub-node of the nxp,pca963x device.
LED sub-node properties:
- label : (optional) see Documentation/devicetree/bindings/leds/common.txt
-- reg : number of LED line (could be from 0 to 3 in pca9632 or pca9633
- or 0 to 7 in pca9634)
+- reg : number of LED line (could be from 0 to 3 in pca9632 or pca9633,
+ 0 to 7 in pca9634, or 0 to 15 in pca9635)
- linux,default-trigger : (optional)
see Documentation/devicetree/bindings/leds/common.txt
Optional properties:
- gpio-controller: allows lines to be used as output-only GPIOs.
-- #gpio-cells: if present, must be 0.
+- #gpio-cells: if present, must not be 0.
Each led is represented as a sub-node of the ti,tca6507 device.
Say Y here if you have a Holtek On Line Grip based game controller
and want to have force feedback support for it.
