If multiple strips are specified, they are "flattened" and sequentialized. For example, if `strip0` and `strip1` with 128 LEDs are specified, the first LED of `strip1` will be treated as the 129th LED. These LEDs are mapped to coordinates according to the layout rule in order. The amount of LEDs must equal the [width * height] value. This property is **required**. * - ``chain-lengths`` - ``array`` - .. code-block:: none Specify the number of LEDs for each strip. It can omit the value if all strip nodes have a `chain-length` property. Each value must be a multiple of the number of LEDs per module [(width / horizontal-modules) * (height / vertical-modules)]. * - ``pixel-format`` - ``int`` - .. code-block:: none Initial Pixel format. See dt-bindings/display/panel.h for a list. This property only accepts PANEL_PIXEL_FORMAT_RGB_888 and PANEL_PIXEL_FORMAT_RRGB_8888. If this property is not set, use PANEL_PIXEL_FORMAT_RGB_888 as a default. Default value: ``1`` .. 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 "led-strip-matrix" compatible. .. list-table:: :widths: 1 1 4 :header-rows: 1 * - Name - Type - Details * - ``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`` - ``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. * - ``zephyr,disabling-power-states`` - ``phandles`` - .. code-block:: none List of power states that will disable this device power. * - ``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**.

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 channels specifiers * - ``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 mailbox / IPM channels specifiers * - ``mbox-names`` - ``string-array`` - .. code-block:: none Provided names of mailbox / IPM channel specifiers * - ``zephyr,deferred-init`` - ``boolean`` - .. code-block:: none Do not initialize device automatically on boot.
