* Freescale MC13783/MC13892 Power Management Integrated Circuit (PMIC)

Required properties:
- compatible : Should be "fsl,mc13783" or "fsl,mc13892"

Optional properties:
- fsl,mc13xxx-uses-adc : Indicate the ADC is being used
- fsl,mc13xxx-uses-codec : Indicate the Audio Codec is being used
- fsl,mc13xxx-uses-rtc : Indicate the RTC is being used
- fsl,mc13xxx-uses-touch : Indicate the touchscreen controller is being used

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