Description
***********
.. code-block:: none
Silicon Labs Series 2 DC-DC converter.
Include the bindings header file to get
access to relevant symbols for configuration.
The following standard properties are supported:
`regulator-boot-on`
Enable DC-DC converter at boot. If not set, the DC-DC converter is powered off.
`regulator-allow-bypass`
Enable bypass mode. If combined with `regulator-boot-on`, the DC-DC converter
is initialized to bypass mode.
`regulator-initial-mode`
DCDC operating mode. One of `SILABS_DCDC_MODE_BUCK` or `SILABS_DCDC_MODE_BOOST`.
`regulator-init-microvolt`
Output voltage for boost mode. Not used in buck mode.

* - Name
- Type
- Details
* - ``regulator-initial-mode``
- ``int``
- .. code-block:: none
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.
Legal values: ``0``, ``1``
* - ``regulator-init-microvolt``
- ``int``
- .. code-block:: none
Voltage set during initialisation
Legal values: ``1800000``, ``1900000``, ``2000000``, ``2100000``, ``2200000``, ``2300000``, ``2400000``
* - ``silabs,pfmx-peak-current-milliamp``
- ``int``
- .. code-block:: none
Peak current draw in PFMX mode (CCM, continuous conduction mode).
Legal values: ``50``, ``65``, ``73``, ``80``, ``86``, ``93``, ``100``, ``106``, ``113``, ``120``
* - ``regulator-boot-on``
- ``boolean``
- .. code-block:: none
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.
* - ``regulator-allow-bypass``
- ``boolean``
- .. code-block:: none
allow the regulator to go into bypass mode
.. group-tab:: Deprecated node specific properties
Deprecated properties not inherited from the base binding file.
(None)
.. group-tab:: 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 "silabs,series2-dcdc" compatible.

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.

the system) by default but they can be enabled at runtime if necessary.
