+LED driver for MAX77650 PMIC from Maxim Integrated.
+
+This module is part of the MAX77650 MFD device. For more details
+see Documentation/devicetree/bindings/mfd/max77650.txt.
+
+The LED controller is represented as a sub-node of the PMIC node on
+the device tree.
+
+This device has three current sinks.
+
+Required properties:
+--------------------
+- compatible: Must be "maxim,max77650-leds"
+- #address-cells: Must be <1>.
+- #size-cells: Must be <0>.
+
+Each LED is represented as a sub-node of the LED-controller node. Up to
+three sub-nodes can be defined.
+
+Required properties of the sub-node:
+------------------------------------
+
+- reg: Must be <0>, <1> or <2>.
+
+Optional properties of the sub-node:
+------------------------------------
+
+- label: See Documentation/devicetree/bindings/leds/common.txt
+- linux,default-trigger: See Documentation/devicetree/bindings/leds/common.txt
+
+For more details, please refer to the generic GPIO DT binding document
+<devicetree/bindings/gpio/gpio.txt>.
+
+Example:
+--------
+
+ leds {
+ compatible = "maxim,max77650-leds";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ led0 {

s/led0/led@0/

+ reg = <0>;
+ label = "max77650:blue:usr0";
+ };
+
+ led1 {

s/led1/led@1/

+ reg = <1>;
+ label = "max77650:red:usr1";
+ linux,default-trigger = "heartbeat";
+ };
+
+ led2 {

s/led2/led@2/

+ reg = <2>;
+ label = "max77650:green:usr2";
+ };

Please remove "max77650:" from labels and add it in the driver.

+ };
