Properties not inherited from the base binding file.

* - Name
- Type
- Details
* - ``counts-per-revolution``
- ``int``
- .. code-block:: none
This is a number that is used to determine how many revolutions
were done based on the current counter's value.
This property is **required**.
* - ``single-phase-mode``
- ``boolean``
- .. code-block:: none
Bypass the quadrature decoder. A positive transition of the PHASEA input
generates a count signal. The PHASEB input and the REV bit control the
counter direction.
* - ``filter-count``
- ``int``
- .. code-block:: none
The number of consecutive samples that must agree prior to the input
filter accepting an input transition. A value of 0 represents 3
samples. A value of 7 represents 10 samples.
Legal values: ``0``, ``1``, ``2``, ``3``, ``4``, ``5``, ``6``, ``7``
* - ``filter-sample-period``
- ``int``
- .. code-block:: none
The sampling period (in IPBus clock cycles) of the decoder input signals.
Each input is sampled multiple times at the rate specified by the Filter
Sample Period. If FILT_PER is 0 (default), then the input filter is
bypassed. Bypassing the digital filter enables the position/position
difference counters to operate with count rates up to the IPBus
frequency. Turning on the input filter introduces a latency of:
((FILT_CNT + 3) * FILT_PER) FILT clock cycles + 2 IPBus clock periods.
* - ``xbar``
- ``phandle``
- .. code-block:: none
The xbar phandle.
This property is **required**.
* - ``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.
* - ``friendly-name``
- ``string``
- .. 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).
.. 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,mcux-qdec" compatible.
.. list-table::

* - Name
- Type
- Details
* - ``reg``
- ``array``
- .. code-block:: none
register space
This property is **required**.
See :ref:`zephyr:dt-important-props` for more information.
* - ``interrupts``
- ``array``
- .. code-block:: none
interrupts for device
This property is **required**.
See :ref:`zephyr:dt-important-props` for more information.
* - ``status``
- ``string``
- .. code-block:: none
indicates the operational status of a device
Legal values: ``'ok'``, ``'okay'``, ``'disabled'``, ``'reserved'``, ``'fail'``, ``'fail-sss'``
See :ref:`zephyr:dt-important-props` for more information.
* - ``compatible``
- ``string-array``
- .. code-block:: none
compatible strings
This property is **required**.
See :ref:`zephyr:dt-important-props` for more information.
* - ``reg-names``
- ``string-array``
- .. code-block:: none
name of each register space
* - ``interrupts-extended``
- ``compound``
- .. code-block:: none
extended interrupt specifier for device
* - ``interrupt-names``
- ``string-array``
- .. code-block:: none
name of each interrupt
* - ``interrupt-parent``
- ``phandle``
- .. code-block:: none
phandle to interrupt controller node
* - ``label``
- ``string``
- .. code-block:: none
Human readable string describing the device (used as device_get_binding() argument)
See :ref:`zephyr:dt-important-props` for more information.
This property is **deprecated**.
* - ``clocks``
- ``phandle-array``
- .. code-block:: none
Clock gate information
* - ``clock-names``
- ``string-array``
- .. code-block:: none
name of each clock
* - ``#address-cells``

- .. code-block:: none
IO channels specifiers
* - ``io-channel-names``
- ``string-array``
- .. code-block:: none
Provided names of IO channel specifiers

- .. code-block:: none
Provided names of mailbox / IPM channel specifiers
* - ``wakeup-source``
- ``boolean``
- .. code-block:: none
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``

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.
