Description
***********
These nodes are "qspi" bus nodes.
.. code-block:: none
STM32 QSPI device representation. A stm32 quadspi node would typically
looks to this:
&quadspi {
pinctrl-0 = <&quadspi_clk_pe10 &quadspi_ncs_pe11
&quadspi_bk1_io0_pe12 &quadspi_bk1_io1_pe13
&quadspi_bk1_io2_pe14 &quadspi_bk1_io3_pe15>;
dmas = <&dma1 5 5 0x0000 0x03>;
dma-names = "tx_rx";
status = "okay";
};
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
* - ``pinctrl-0``
- ``phandles``
- This property is **required**.
.. 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 "st,stm32-qspi" compatible.
.. list-table::
:widths: 1 1 4
:header-rows: 1
* - 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.
* - ``dmas``
- ``phandle-array``
- .. code-block:: none
Optional DMA channel specifier. If DMA should be used, specifier should
hold a phandle reference to the dma controller, the channel number,
the slot number, channel configuration and finally features.
For example dmas for TX/RX on QSPI
dmas = <&dma1 5 5 0x0000 0x03>;
* - ``dma-names``
- ``string-array``
- .. code-block:: none
DMA channel name. If DMA should be used, expected value is "tx_rx".
For example
dma-names = "tx_rx";
* - ``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.
* - ``clocks``

- .. code-block:: none
number of address cells in reg property
* - ``#size-cells``
- ``int``
- .. code-block:: none
number of size cells in reg property
* - ``io-channels``
- ``phandle-array``
- .. code-block:: none
IO channels specifiers
* - ``io-channel-names``
- ``string-array``
- .. code-block:: none
Provided names of IO 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.
