Description

.. code-block:: none
Bindings for HID device
Properties
**********
.. tabs::
.. group-tab:: Node specific properties
Properties not inherited from the base binding file.
.. list-table::
:widths: 1 1 4
:header-rows: 1
* - Name
- Type
- Details
* - ``interface-name``
- ``string``
- .. code-block:: none
HID device name. When this property is present, a USB device will use it
as the string descriptor of the interface.
* - ``protocol-code``
- ``string``
- .. code-block:: none
This property corresponds to the protocol codes defined in Chapter 4.3
of the HID specification. Only boot devices are required to set one of
the protocols, keyboard or mouse. For non-boot devices, this property is
not required or can be set to none.
- none: Device does not support the boot interface
- keyboard: Device supports boot interface and keyboard protocol
- mouse: Device supports boot interface and mouse protocol
Legal values: ``'none'``, ``'keyboard'``, ``'mouse'``
* - ``in-report-size``
- ``int``
- .. code-block:: none
The size of the longest input report that the HID device can generate.
This property is used to determine the buffer length used for transfers.
This property is **required**.
* - ``in-polling-period-us``
- ``int``
- .. code-block:: none
Input or output type reports polling period in microseconds. For USB full
speed this could be clamped to 1ms or 255ms depending on the value.
This property is **required**.
* - ``out-report-size``
- ``int``
- .. code-block:: none
The size of the longest output report that the HID device can generate.
When this property is present, a USB device will use out pipe for output
reports, otherwise control pipe will be used for output reports.
* - ``out-polling-period-us``
- ``int``
- .. code-block:: none
Output type reports polling period in microseconds. For USB full
speed this could be clamped to 1ms or 255ms depending on the value.
This option is only effective if the out-report-size property is defined.
.. 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 "zephyr,hid-device" compatible.
.. list-table::
:widths: 1 1 4
:header-rows: 1
* - Name
- Type
- Details
* - ``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``
- ``array``
- .. code-block:: none
register space
See :ref:`zephyr:dt-important-props` for more information.
* - ``reg-names``
- ``string-array``
- .. code-block:: none
name of each register space
* - ``interrupts``
- ``array``
- .. code-block:: none
interrupts for device
See :ref:`zephyr:dt-important-props` for more information.
* - ``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``
- ``int``
- .. code-block:: none
number of address cells in reg property
* - ``#size-cells``
- ``int``
- .. code-block:: none
number of size cells in reg property
* - ``dmas``
- ``phandle-array``
- .. code-block:: none

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

- ``int``
- .. code-block:: none
Number of cells in power-domains property
* - ``zephyr,deferred-init``
- ``boolean``
- .. code-block:: none
Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
* - ``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.
* - ``zephyr,pm-device-runtime-auto``
- ``boolean``
- .. code-block:: none
Automatically configure the device for runtime power management after the
init function runs.
* - ``zephyr,disabling-power-states``
- ``phandles``
- .. code-block:: none
List of power states that will disable this device power.
