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;
|
||||
};
|
||||
...
|
