Marvell 88PM800 regulator
Required properties:
- compatible: "marvell,88pm800"
- reg: I2C slave address
- regulators: A node that houses a sub-node for each regulator within the
device. Each sub-node is identified using the node's name (or the deprecated
regulator-compatible property if present), with valid values listed below.
The content of each sub-node is defined by the standard binding for
regulators; see regulator.txt.
The valid names for regulators are:
buck1, buck2, buck3, buck4, buck5, ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7,
ldo8, ldo9, ldo10, ldo11, ldo12, ldo13, ldo14, ldo15, ldo16, ldo17, ldo18, ldo19
Example:
pmic: 88pm800@31 {
compatible = "marvell,88pm800";
reg = <0x31>;
regulators {
buck1 {
regulator-min-microvolt = <600000>;
regulator-max-microvolt = <3950000>;
regulator-boot-on;
regulator-always-on;
};
ldo1 {
regulator-min-microvolt = <600000>;
regulator-max-microvolt = <15000000>;
regulator-boot-on;
regulator-always-on;
};
...
};
};
