 Sub-nodes:
+- leds : Contain the led nodes and initial register values in property
+  "led-control". Number of register depends of used IC, for MC13783 is 6,
+  for MC13892 is 4, for MC34708 is 1. See datasheet for bits definitions of

+  - #address-cells: Must be 1.
+  - #size-cells: Must be 0.
+  Each led node should contain "reg", which used as LED ID (described below).
+  Optional properties "label" and "linux,default-trigger" is described in
+  Documentation/devicetree/bindings/leds/common.txt.
 - regulators : Contain the regulator nodes. The regulators are bound using
   their names as listed below with their registers and bits for enabling.
