-Regulator driver for MAX77650 PMIC from Maxim Integrated.
-
-This module is part of the MAX77650 MFD device. For more details
-see Documentation/devicetree/bindings/mfd/max77650.txt.
-
-The regulator controller is represented as a sub-node of the PMIC node
-on the device tree.
-
-The device has a single LDO regulator and a SIMO buck-boost regulator with
-three independent power rails.
-
-Required properties:
---------------------
-- compatible:		Must be "maxim,max77650-regulator"
-
-Each rail must be instantiated under the regulators subnode of the top PMIC
-node. Up to four regulators can be defined. For standard regulator properties
-refer to Documentation/devicetree/bindings/regulator/regulator.txt.
-
-Available regulator compatible strings are: "ldo", "sbb0", "sbb1", "sbb2".
-
-Example:
---------
-
-	regulators {
-		compatible = "maxim,max77650-regulator";
-
-		max77650_ldo: regulator@0 {
-			regulator-compatible = "ldo";
-			regulator-name = "max77650-ldo";
-			regulator-min-microvolt = <1350000>;
-			regulator-max-microvolt = <2937500>;
-		};
-
-		max77650_sbb0: regulator@1 {
-			regulator-compatible = "sbb0";
-			regulator-name = "max77650-sbb0";
-			regulator-min-microvolt = <800000>;
-			regulator-max-microvolt = <1587500>;
-		};
