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	- regulators : Contain the regulator nodes.  The MC13892 regulators are
14	  bound using their names as listed below with their registers and bits
15	  for enabling.
