Which is ok, because generic code adds "-gpios" itself.

It controls power of the chip. Noone gets _power_ through gpios,
hopefully. Yes, I can rename it. "en-gpios" is too ugly to
live. Sebastian suggested "enable". Hope that's okay with you.

+* Analog Devices ADP1653 flash LED driver
+
+Required Properties:
+
+ - compatible: Must contain be "adi,adp1653"
+
+ - reg: I2C slave address
+
+ - power-gpios: Reference 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>;
+ power-gpios = <&gpio3 24 GPIO_ACTIVE_HIGH>; /* 88 */
+
+ flash {
+ flash-timeout-us = <500000>;
+ flash-max-microamp = <320000>;
+ max-microamp = <50000>;
+ };
+ indicator {
+ max-microamp = <17500>;
+ };
+ };
