3Required properties:
4- compatible : Should be "fsl,mc13783" or "fsl,mc13892"
5
6Optional properties:
7- fsl,mc13xxx-uses-adc : Indicate the ADC is being used
8- fsl,mc13xxx-uses-codec : Indicate the Audio Codec is being used
9- fsl,mc13xxx-uses-rtc : Indicate the RTC is being used
10- fsl,mc13xxx-uses-touch : Indicate the touchscreen controller is being used
11
12Sub-nodes:
13- leds : Contain the led nodes and initial register values in property
14  "led-control". Number of register depends of used IC, for MC13783 is 6,
15  for MC13892 is 4, for MC34708 is 1. See datasheet for bits definitions of
16  these registers.
17  - #address-cells: Must be 1.
18  - #size-cells: Must be 0.
19  Each led node should contain "reg", which used as LED ID (described below).
20  Optional properties "label" and "linux,default-trigger" is described in
21  Documentation/devicetree/bindings/leds/common.txt.
22- regulators : Contain the regulator nodes. The regulators are bound using
23  their names as listed below with their registers and bits for enabling.
