+Bindings for Linear Technologies LT3593 LED controller
+
+Required properties:
+- compatible : should be "lltc,lt3593".
+- label: A label for the LED.
+
+Optional properties:
+- linux,default-trigger : (optional)
+ see Documentation/devicetree/bindings/leds/common.txt
+- default-state: (optional) The initial state of the LED.
+ see Documentation/devicetree/bindings/leds/common.txt
+
+The controller only suports one LED, hence the properties are all set
+in the root node of the device. If multiple chips of this kind are
+found in a design, each one needs to be handled by its own device node.
+
+Example:
+
+led-controller {
+ compatible = "lltc,lt3593";
+ label = "led-stripe";
+ gpios = <&gpio 0 GPIO_ACTIVE_HIGH>;
+ linux,default-trigger = "heartbeat";
+};
