- .. code-block:: none
Human readable string describing the sensor. It can be used to
distinguish multiple instances of the same model (e.g., lid accelerometer
vs. base accelerometer in a laptop) to a host operating system.
This property is defined in the Generic Sensor Property Usages of the HID
Usage Tables specification
(https://usb.org/sites/default/files/hut1_3_0.pdf, section 22.5).
* - ``pinctrl-0``
- ``phandles``
- .. code-block:: none
Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.
* - ``pinctrl-1``
- ``phandles``
- .. code-block:: none
Pin configuration/s for the second state. See pinctrl-0.
* - ``pinctrl-2``
- ``phandles``
- .. code-block:: none
Pin configuration/s for the third state. See pinctrl-0.
* - ``pinctrl-3``
- ``phandles``
- .. code-block:: none
Pin configuration/s for the fourth state. See pinctrl-0.
* - ``pinctrl-4``
- ``phandles``
- .. code-block:: none
Pin configuration/s for the fifth state. See pinctrl-0.
* - ``pinctrl-names``
- ``string-array``
- .. code-block:: none
Names for the provided states. The number of names needs to match the
number of states.
.. 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 "nxp,kinetis-acmp" compatible.

See :ref:`dt-important-props` for more information.
* - ``compatible``
- ``string-array``

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``
- ``phandle``
- .. code-block:: none
Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
* - ``zephyr,pm-device-runtime-auto``
- ``boolean``
- .. code-block:: none
Automatically configure the device for runtime power management after the
init function runs.
