14 LED and flash LED devices provide the same basic functionality as current
15 regulators, but extended with LED and flash LED specific features like
18 Many LED devices expose more than one current output that can be connected
19 to one or more discrete LED component. Since the arrangement of connections
20 can influence the way of the LED device initialization, the LED components
21 have to be tightly coupled with the LED device binding. They are represented
22 by child nodes of the parent LED device binding.
