   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
