Description *********** These nodes are "mipi-dbi" bus nodes. .. code-block:: none MIPI-DBI Mode C compatible SPI controller. This driver emulates MIPI DBI mode C using a SPI controller and GPIO pins 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 * - ``spi-dev`` - ``phandle`` - .. code-block:: none SPI device to use for data transfers with MIPI DBI commands. This SPI device should be connected to the MIPI DBI display. This property is **required**. * - ``dc-gpios`` - ``phandle-array`` - .. code-block:: none Data/command gpio pin. Required when using 4 wire SPI mode (Mode C1). Set to low when sending a command, or high when sending data. * - ``reset-gpios`` - ``phandle-array`` - .. code-block:: none Reset GPIO pin. Set high to reset the display * - ``xfr-min-bits`` - ``int`` - .. code-block:: none On rare types of SPI interfaces, discrete shift registers can be found whose task is to convert the serial SPI bit stream to the parallel MCU interface with clock and bit accuracy. Typically, these are 16 bits wide. Use the macros, not the actual enum value. Here is the concordance list (see dt-bindings/mipi_dbi/mipi_dbi.h) 8 MIPI_DBI_SPI_XFR_8BIT 16 MIPI_DBI_SPI_XFR_16BIT Default value: ``8`` Legal values: ``8``, ``16`` * - ``write-only`` - ``boolean`` - .. code-block:: none Only writes to display controller, do not perform reads. If all controllers are write-only, read functions will be optimized out for size. It can also be used as an alternative to half duplex when only one data line is connected. * - ``clock-frequency`` - ``int`` - .. code-block:: none Clock frequency of the SCL signal of the MBI-DBI peripheral, in Hz * - ``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. .. 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,mipi-dbi-spi" compatible. .. list-table:: :widths: 1 1 4 :header-rows: 1 * - Name - Type - Details * - ``#address-cells`` - ``int`` - .. code-block:: none number of address cells in reg property This property is **required**. Constant value: ``1`` * - ``#size-cells`` - ``int`` - .. code-block:: none number of size cells in reg property This property is **required**. * - ``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 * - ``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 * - ``power-domains`` - ``phandle-array`` - .. code-block:: none Power domain specifiers * - ``power-domain-names`` - ``string-array`` - .. code-block:: none Provided names of power domain specifiers * - ``#power-domain-cells`` - ``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.
