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.

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>;
