+* Analog Devices ADP1653 flash LED driver
+
+Required Properties:
+
+ - compatible: Must contain "adi,adp1653"
+
+ - reg: I2C slave address
+
+ - enable-gpios: Specifier of the GPIO connected to EN pin
+
+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:

+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:

- Enables dt3155 device driver for the DataTranslation DT3155 frame grabber.
- Say Y here if you have this hardware.
- In doubt, say N.
-
- To compile this driver as a module, choose M here: the
