+Bindings for Linear Technologies LT3593 LED controller
+
+Required properties:
+- compatible: Should be "lltc,lt3593".
+- lltc,ctrl-gpios: A handle to the GPIO that is connected to the 'CTRL'
+ pin of the chip.
+
+The hardware supports only one LED. The properties of this LED are
+configured in a sub-node in the device node.
+
+Optional sub-node properties:
+- label: A label for the LED. If none is given, the LED will be
+ named "lt3595::".
+- linux,default-trigger: The default trigger for the LED.
+ See Documentation/devicetree/bindings/leds/common.txt
+- default-state: The initial state of the LED.
+ See Documentation/devicetree/bindings/leds/common.txt
+
+If multiple chips of this type are found in a design, each one needs to
+be handled by its own device node.
+
+Example:
+
+led-controller {
+ compatible = "lltc,lt3593";
+ lltc,ctrl-gpios = <&gpio 0 GPIO_ACTIVE_HIGH>;
+
+ led {
+ label = "white:backlight";
+ default-state = "on";
+ };
+};
