    2 
    3 Required properties:
    4 - compatible: Should one of contain:
    5         "nxp,pca85073a",
    6         "nxp,pcf85063",

    9         "microcrystal,rv8263"
   10 - reg: I2C address for chip.
   11 
   12 Optional property:
   13 - quartz-load-femtofarads: The capacitive load of the quartz(x-tal),
   14   expressed in femto Farad (fF). Valid values are 7000 and 12500.
   15   Default value (if no value is specified) is 7000fF.
