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>;
};
};
