Vendor: Maxim Integrated Products
Description
Maxim MAX20335 PMIC
The PMIC has two buck converters and three LDOs. All need to be defined as
children nodes, strictly following the BUCK1..2, LDO1..3 node names. For
example:
pmic@28 {
reg = <0x28>;
...
regulators {
compatible = maxim,max20335-regulator";
BUCK1 {
/* all properties for BUCK1 */
};
BUCK2 {
/* all properties for BUCK2 */
};
LDO1 {
/* all properties for LDO1 */
};
LDO2 {
/* all properties for LDO2 */
};
LDO3 {
/* all properties for LDO3 */
};
};
};
Properties
Top level properties
These property descriptions apply to “maxim,max20335-regulator” nodes themselves. This page also describes child node properties in the following sections.
Properties not inherited from the base binding file.
(None)
Deprecated properties not inherited from the base binding file.
(None)
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “maxim,max20335-regulator” compatible.

Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.

|
|
List of power states that will disable this device power.

bootloader/firmware enabled regulator.
It's expected that this regulator was left on by the bootloader.
If the bootloader didn't leave it on then OS should turn it on
at boot but shouldn't prevent it from being turned off later.
This property is intended to only be used for regulators where
software cannot read the state of the regulator.
|
|
|
Initial operating mode. The set of possible operating modes depends on the
capabilities of every hardware so each device binding documentation
explains which values the regulator supports.
|
|
|
List of operating modes that software is allowed to configure for the
regulator at run-time. Elements may be specified in any order. The set of
possible operating modes depends on the capabilities of every hardware so
each device binding document explains which values the regulator supports.
