Vendor: Generic or vendor-independent
Description
PMIC controlled regulator
Properties
Top level properties
These property descriptions apply to “regulator-pmic” nodes themselves. This page also describes child node properties in the following sections.
Properties not inherited from the base binding file.

|---|---|---|
|
|
Initial operating mode of the regulator. Regulators modes can be
used for better power saving, or different voltage configurations,
and are hardware specific.
|
|
|
Array of operating modes that software may configure for the
regulator at runtime. The set of possible operating modes depends on
what the hardware supports.
|
|
|
Mode selection register. This register is used by the regulator driver
to select the target mode of the regulator
|
|
|
Mode selection mask. Applied to a mode selection when it is written
to the modesel-reg.
|
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 “regulator-pmic” 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.

|
|
array of voltage values in uV, followed by the register value that
must be written to enable the voltage. For example, [3300000, 0x3]
denotes a value of 0x3 must be written to the register to set 3.3V
This property is required. |
|
|
number of voltages present in the voltage-range array.
This property is required. |
|
|
I2C register to write voltage selection value to
This property is required. |
|
|
Mask to apply to the voltage range value when written to vsel
register
This property is required. |
|
|
I2C register to write enable value to
This property is required. |
|
|
Mask to apply to the enable bit (either 1 for enabled,
or 0 for disabled) when writing it to the I2C enable register.
This property is required. |
|
|
value to apply enable-mask to, and write to enable-reg in order
to enable the regulator output.
This property is required. |
|
|
Minimum voltage in microvolts that this regulator supports
This property is required. |
|
|
Maximum voltage in microvolts that this regulator supports
This property is required. |
|
|
If the enable bit should be zero to turn the regulator on, add this
property.
|
|
|
Array of current limit values in uA, followed by the register value
that must be written to enable the current limit. For example,
[800000, 0x3] denotes a value of 0x3 must be written to the register
to set a current limit of 800mA
|
|
|
Number of current limit levels this regulator supports. If left as
default, regulator current support will be disabled.
|
|
|
Register to write the register value given in current-levels into
to set the current limit
|
|
|
Mask to apply to the current-levels value before writing it to the
ilim-reg value to set the current limit
|
|
|
regulator should be turned on at startup
