3 LED and flash LED devices provide the same basic functionality as current
4 regulators, but extended with LED and flash LED specific features like
7 Many LED devices expose more than one current output that can be connected
8 to one or more discrete LED component. Since the arrangement of connections
9 can influence the way of the LED device initialization, the LED components
10 have to be tightly coupled with the LED device binding. They are represented
11 by child nodes of the parent LED device binding.

17 - label : The label for this LED. If omitted, the label is taken from the node
19 	  a device, i.e. no other LED class device can be assigned the same
23     string defining the trigger assigned to the LED.  Current triggers are:
24      "backlight" - LED will act as a back-light, controlled by the framebuffer
26      "default-on" - LED will turn on (but for leds-gpio see "default-state"
28      "heartbeat" - LED "double" flashes at a load average based rate
29      "ide-disk" - LED indicates disk activity
30      "timer" - LED flashes at a fixed, configurable rate
32 - led-max-microamp : Maximum LED supply current in microamperes. This property
