-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
-
-  - clock-names : must contain "MCLK"
-
-Example:
-
-cs42l51: cs42l51@4a {
-	compatible = "cirrus,cs42l51";
-	reg = <0x4a>;
-	clocks = <&mclk_prov>;
