+* Analog Devices ADP1653 flash LED driver
+
+Required Properties:
+
+  - compatible: Must contain be "adi,adp1653"
+
+  - reg: I2C slave address
+
+  - gpios: References to the GPIO that controls the power for the chip.
+
+There are two led outputs available - flash and indicator. One led is
+represented by one child node, nodes need to be named "flash" and "indicator".
+
+Required properties of the LED child node:
+- max-microamp : see Documentation/devicetree/bindings/leds/common.txt
+
+Required properties of the flash LED child node:
+
+- flash-max-microamp : see Documentation/devicetree/bindings/leds/common.txt
+- flash-timeout-us : see Documentation/devicetree/bindings/leds/common.txt
+
+Example:
+
+       adp1653: led-controller@30 {
+               compatible = "adi,adp1653";
+               reg = <0x30>;
+               gpios = <&gpio3 24 GPIO_ACTIVE_HIGH>; /* 88 */
+
+               flash {
+                       flash-timeout-us = <500000>;
+                       flash-max-microamp = <320000>;
+                       max-microamp = <50000>;
+               };
+               indicator {
+                       max-microamp = <17500>;
+               };
+       };
