+Binding for dual-GPIO LED found on Network Space v2 (and parents).
+
+Required properties:
+- compatible: "lacie,ns2-leds".
+
+Each LED is represented as a sub-node of the ns2-leds device.
+
+Required sub-node properties:
+- cmd-gpio: Command LED GPIO. See OF device-tree GPIO specification.
+- slow-gpio: Slow LED GPIO. See OF device-tree GPIO specification.
+- modes-map: A mapping between LED modes (off, on or SATA activity blinking) and
+  the corresponding cmd-gpio/slow-gpio values. All the GPIO values combinations
+  should be given in order to avoid having an unknown mode at driver probe time.
+
+Optional sub-node properties:
+- label: Name for this LED. If omitted, the label is taken from the node name.
+- linux,default-trigger: Trigger assigned to the LED.
+
+Example:
+
+#include <dt-bindings/leds/leds-ns2.h>
+
+ns2-leds {
+	compatible = "lacie,ns2-leds";
+
+	blue-sata {
+		label = "ns2:blue:sata";
+		slow-gpio = <&gpio0 29 0>;
+		cmd-gpio = <&gpio0 30 0>;
+		modes-map = <NS_V2_LED_OFF  0 1
+			     NS_V2_LED_ON   1 0
+			     NS_V2_LED_ON   0 0
+			     NS_V2_LED_SATA 1 1>;
+	};
+};
