1	Binding for dual-GPIO LED found on Network Space v2 (and parents).
2	
3	Required properties:
4	- compatible: "lacie,ns2-leds".
5	
6	Each LED is represented as a sub-node of the ns2-leds device.
7	
8	Required 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	
15	Optional 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	
19	Example:
20	
21	#include <dt-bindings/leds/leds-ns2.h>
22	
23	ns2-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		};
35	};
