1Binding for dual-GPIO LED found on Network Space v2 (and parents).
2
3Required properties:
4- compatible: "lacie,ns2-leds".
5
6Each LED is represented as a sub-node of the ns2-leds device.
7
8Required sub-node properties:
9- cmd-gpio: Command LED GPIO. See OF device-tree GPIO specification.
10- slow-gpio: Slow LED GPIO. See OF device-tree GPIO specification.
11- modes-map: A mapping between LED modes (off, on or SATA activity blinking) and
12  the corresponding cmd-gpio/slow-gpio values. All the GPIO values combinations
13  should be given in order to avoid having an unknown mode at driver probe time.
14
15Optional sub-node properties:
16- label: Name for this LED. If omitted, the label is taken from the node name.
17- linux,default-trigger: Trigger assigned to the LED.
18
19Example:
20
21#include <dt-bindings/leds/leds-ns2.h>
22
23ns2-leds {
24	compatible = "lacie,ns2-leds";
25
26	blue-sata {
27		label = "ns2:blue:sata";
28		slow-gpio = <&gpio0 29 0>;
29		cmd-gpio = <&gpio0 30 0>;
30		modes-map = <NS_V2_LED_OFF  0 1
31			     NS_V2_LED_ON   1 0
32			     NS_V2_LED_ON   0 0
33			     NS_V2_LED_SATA 1 1>;
34	};
