    5   - compatible : must contain one of "cirrus,cs42448" and "cirrus,cs42888"
    6 
    7   - reg : the I2C address of the device for I2C
    8 
    9   - clocks : a list of phandles + clock-specifiers, one for each entry in
   10     clock-names
   11 
   12   - clock-names : must contain "mclk"
   13 
   14   - VA-supply, VD-supply, VLS-supply, VLC-supply: power supplies for the device,
   15     as covered in Documentation/devicetree/bindings/regulator/regulator.txt
   16 
   17 Optional properties:

   22 Example:
   23 
   24 cs42888: codec@48 {
   25         compatible = "cirrus,cs42888";
   26         reg = <0x48>;
   27         clocks = <&codec_mclk 0>;
