+
+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
