    4 
    5 Required properties:
    6 - compatible : Should be "dlg,da7212" or "dlg,da7213"
    7 - reg: Specifies the I2C slave address
    8 
    9 Optional properties:
   10 - clocks : phandle and clock specifier for codec MCLK.
   11 - clock-names : Clock name string for 'clocks' attribute, should be "mclk".
   12 
   13 - dlg,micbias1-lvl : Voltage (mV) for Mic Bias 1
