Common leds properties.

Optional properties for child nodes:

• label : The label for this LED. If omitted, the label is
  taken from the node name (excluding the unit address).

• linux,default-trigger : This parameter, if present, is a
  string defining the trigger assigned to the LED. Current triggers are:
  “backlight” - LED will act as a back-light, controlled by the framebuffer

       system
  

  “default-on” - LED will turn on (but for leds-gpio see “default-state”

        property in Documentation/devicetree/bindings/gpio/led.txt)
  

  “heartbeat” - LED “double” flashes at a load average based rate
  “ide-disk” - LED indicates disk activity
  “timer” - LED flashes at a fixed, configurable rate

Examples:

system-status {
label = “Status”;
linux,default-trigger = “heartbeat”;
…
};
