+
+Required properties:
+ - compatible : should be one of
+		"adi,ad5933"
+		"adi,ad5934"
+ - reg : the I2C address.
+ - vdd-supply : The regulator supply for DVDD, AVDD1 and AVDD2 when they
+   are connected together.
+
+Optional properties:
+- clocks : external clock reference.
+- clock-names : must be "mclk" if clocks is set.
+
+Example for a I2C device node:
+
+	impedance-analyzer@0d {
+		compatible = "adi,adxl345";
+		reg = <0x0d>;
+		vdd-supply = <&vdd_supply>;
+		clocks = <&ref_clk>;
+		clock-names = "mclk";
+	};
