nxp,vref
Vendor: NXP Semiconductors N.V.
Note
An implementation of a driver matching this compatible is available in drivers/regulator/regulator_nxp_vref.c.
Description
NXP VREF SOC peripheral
Properties
Node specific properties
Properties not inherited from the base binding file.
Name |
Type |
Details |
|---|---|---|
|
|
Buffer startup delay as specified in the
appropriate device data sheet, in microseconds.
This property is required. |
|
|
Maximum bandgap startup time as specified in the
appropriate device data sheet, in microseconds.
This property is required. |
|
|
Enable second-order curvature compensation.
This must be enabled to achieve the performance stated in the datasheet.
However, the reset value of the peripheral has it disabled.
|
|
|
Number of items to expect in a vref specifier.
Constant value: |
|
|
A string used as a descriptive name for regulator outputs
|
|
|
Voltage set during initialisation
|
|
|
smallest voltage consumers may set
|
|
|
largest voltage consumers may set
|
|
|
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.
|
Deprecated node specific properties
Deprecated properties not inherited from the base binding file.
(None)
Base properties
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 “nxp,vref” compatible.

|
Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
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.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
|
|
|
List of power states that will disable this device power.
