CS42L51 audio CODEC
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
