Annotated Snippet

Required properties:
- compatible: Must be one of the following, depending on the
  silicon version:
	- "pvs,pv88080" (DEPRECATED)

	- "pvs,pv88080-aa" for PV88080 AA or AB silicon
	- "pvs,pv88080-ba" for PV88080 BA or BB silicon
  NOTE: The use of the compatibles with no silicon version is deprecated.
- reg: I2C slave address, usually 0x49
- interrupts: the interrupt outputs of the controller
- regulators: A node that houses a sub-node for each regulator within the
  device. Each sub-node is identified using the node's name, with valid
  values listed below. The content of each sub-node is defined by the
  standard binding for regulators; see regulator.txt.
  BUCK1, BUCK2, BUCK3 and HVBUCK.

Optional properties:
- Any optional property defined in regulator.txt

Example:

	pmic: pv88080@49 {
		compatible = "pvs,pv88080-ba";
		reg = <0x49>;
		interrupt-parent = <&gpio>;
		interrupts = <24 24>;

		regulators {
			BUCK1 {
				regulator-name = "buck1";
				regulator-min-microvolt = < 600000>;
				regulator-max-microvolt = <1393750>;
				regulator-min-microamp 	= < 220000>;
				regulator-max-microamp 	= <7040000>;
			};

			BUCK2 {
				regulator-name = "buck2";
				regulator-min-microvolt = < 600000>;
				regulator-max-microvolt = <1393750>;
				regulator-min-microamp 	= <1496000>;
				regulator-max-microamp 	= <4189000>;
			};

			BUCK3 {
				regulator-name = "buck3";
				regulator-min-microvolt = <1400000>;
				regulator-max-microvolt = <2193750>;
				regulator-min-microamp 	= <1496000>;
				regulator-max-microamp 	= <4189000>;
			};

			HVBUCK {
				regulator-name = "hvbuck";
				regulator-min-microvolt = <   5000>;
				regulator-max-microvolt = <1275000>;
 			};
		};
