-Required properties:
-
- - compatible : "cirrus,cs42l51"
-
- - reg : the I2C address of the device for I2C.
-
-Optional properties:
- - VL-supply, VD-supply, VA-supply, VAHP-supply: power supplies for the device,
- as covered in Documentation/devicetree/bindings/regulator/regulator.txt.
-
- - reset-gpios : GPIO specification for the reset pin. If specified, it will be
- deasserted before starting the communication with the codec.
-
- - clocks : a list of phandles + clock-specifiers, one for each entry in
- clock-names
-
- - clock-names : must contain "MCLK"
