Properties
Properties not inherited from the base binding file.

|
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 always be on
|
|
|
regulator should be turned on at startup
|
|
|
GPIO specifier that controls power to the device.
This property should be provided when the device has a dedicated
switch that controls power to the device. The supply state is
entirely the responsibility of the device driver.
Contrast with vin-supply.
|
|
|
Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.
This property should be provided when device power is supplied
by a shared regulator. The supply state is dependent on the
request status of all devices fed by the regulator.
Contrast with supply-gpios. If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.
|
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.
