1	* Freescale MC13783/MC13892 Power Management Integrated Circuit (PMIC)
2	
3	Required properties:
4	- compatible : Should be "fsl,mc13783" or "fsl,mc13892"
5	
6	Optional 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	
12	Sub-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.
