      .. list-table::
         :widths: 1 1 4
         :header-rows: 1

         * - Name
           - Type
           - Details

         * - ``supply-gpios``
           - ``phandle-array``
           - .. code-block:: none

                GPIO specifier that controls power to the device.

                This property should be provided when the device has a dedicated
                switch that controls power to the device.  The supply state is
                entirely the responsibility of the device driver.

                Contrast with vin-supply.



         * - ``vin-supply``
           - ``phandle``
           - .. code-block:: none

                Reference to the regulator that controls power to the device.
                The referenced devicetree node must have a regulator compatible.

                This property should be provided when device power is supplied
                by a shared regulator.  The supply state is dependent on the
                request status of all devices fed by the regulator.

                Contrast with supply-gpios.  If both properties are provided
                then the regulator must be requested before the supply GPIOS is
                set to an active state, and the supply GPIOS must be set to an
                inactive state before releasing the regulator.



         * - ``mipi-max-frequency``
           - ``int``
           - .. code-block:: none

                Maximum clock frequency of device's MIPI interface in Hz


         * - ``mipi-mode``
           - ``int``
           - .. code-block:: none

                MIPI DBI mode in use. Use the macros, not the actual enum value. Here is
                the concordance list (see dt-bindings/mipi_dbi/mipi_dbi.h)
                  1     MIPI_DBI_MODE_SPI_3WIRE
                  2     MIPI_DBI_MODE_SPI_4WIRE
                  3     MIPI_DBI_MODE_6800_BUS_16_BIT
                  4     MIPI_DBI_MODE_6800_BUS_9_BIT
                  5     MIPI_DBI_MODE_6800_BUS_8_BIT
                  6     MIPI_DBI_MODE_8080_BUS_16_BIT
                  7     MIPI_DBI_MODE_8080_BUS_9_BIT
                  8     MIPI_DBI_MODE_8080_BUS_8_BIT



             Legal values: ``1``, ``2``, ``3``, ``4``, ``5``, ``6``, ``7``, ``8``

         * - ``duplex``
           - ``int``
           - .. code-block:: none

                SPI Duplex mode, full or half. By default it's always full duplex thus 0
                as this is, by far, the most common mode.
                Selecting half duplex allows to use SPI MOSI as a bidirectional line,
                typically used when only one data line is connected.
                Use the macros not the actual enum value, here is the concordance
                list (see dt-bindings/spi/spi.h)
                  0    SPI_FULL_DUPLEX
                  2048 SPI_HALF_DUPLEX



         * - ``mipi-cpol``
           - ``boolean``
           - .. code-block:: none

                SPI clock polarity which indicates the clock idle state.
                If it is used, the clock idle state is logic high; otherwise, low.



         * - ``mipi-cpha``
           - ``boolean``
           - .. code-block:: none

                SPI clock phase that indicates on which edge data is sampled.
                If it is used, data is sampled on the second edge; otherwise, on the first edge.



         * - ``mipi-hold-cs``
           - ``boolean``
           - .. code-block:: none

                In some cases, it is necessary for the master to manage SPI chip select
                under software control, so that multiple spi transactions can be performed
                without releasing it. A typical use case is variable length SPI packets
                where the first spi transaction reads the length and the second spi transaction
                reads length bytes.



         * - ``height``
           - ``int``
           - .. code-block:: none

                Height of the panel driven by the controller, with the units in pixels.



             This property is **required**.

           - ``int``
           - .. code-block:: none

                Width of the panel driven by the controller, with the units in pixels.



             This property is **required**.

           - ``int``
           - .. code-block:: none

                Display pixel format. Note that when RGB888 pixel format is selected only 6 color bits are actually used being in practice equivalent to RGB666.


             Legal values: ``0``, ``1``

         * - ``rotation``
           - ``int``
           - .. code-block:: none

                Display rotation (CW) in degrees. If not defined, rotation is off by default.


             Legal values: ``0``, ``90``, ``180``, ``270``

         * - ``display-inversion``
           - ``boolean``
           - .. code-block:: none

         * - ``pwctrl1``
           - ``uint8-array``
