Bindings/leds/leds-ns2.txt

   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.

  21 #include <dt-bindings/leds/leds-ns2.h>

  23 ns2-leds {
  24         compatible = "lacie,ns2-leds";

  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
