- .. code-block:: none
Initial clock frequency in Hz
.. 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 "atmel,sam0-i2c" compatible.

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.
* - ``clocks``

- .. code-block:: none
name of each clock
This property is **required**.
* - ``dmas``
- ``phandle-array``
- .. code-block:: none
Optional TX & RX dma specifiers. Each specifier will have a phandle
reference to the dmac controller, the channel number, and peripheral
trigger source.
For example dmas for TX, RX on SERCOM3
dmas = <&dmac 0 0xb>, <&dmac 0 0xa>;
* - ``dma-names``
- ``string-array``
- .. code-block:: none
Required if the dmas property exists. This should be "tx" and "rx"
to match the dmas property.
For example
dma-names = "tx", "rx";
* - ``#address-cells``
- ``int``
- .. code-block:: none
number of address cells in reg property
This property is **required**.
Constant value: ``1``

number of size cells in reg property
This property is **required**.
* - ``label``
- ``string``
- .. code-block:: none
Human readable string describing the device (used as device_get_binding() argument)
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``
