    +Analog Devices AD7746/5/7 capacitive sensor driver
    +
    +Required properties:
    + - compatible: Should be one of
    + * "adi,ad7745"
    + * "adi,ad7746"
    + * "adi,ad7747"
    + - reg: The 7-bits long I2c address of the device
    +
    +Optional properties:
    + - adi,exclvl: This property defines the excitation voltage level for the
    + capacitance to be measured. Possible values are:
    + * 0 = +-VDD/8
    + * 1 = +-VDD/4
    + * 2 = +-VDD * 3/8
    + * 3 = +-VDD/2 (Default)
    + - adi,nexca_en: Invert excitation output A.
    + - adi,nexcb_en: Invert excitation output B.
    +
    +Example:
    +Here exclvl would be 1 (VDD/4), Excitation pin A would be inverted and
    +Excitation pin B would NOT be inverted.
