           - ``string-array``
           - .. code-block:: none

                Names for the provided states. The number of names needs to match the
                number of states.



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

                Reset GPIO pin. Used to reset the display during initialization.



         * - ``te-enable``
           - ``boolean``
           - .. code-block:: none

                Boolean to indicate whether the tearing effect (TE) signal is available or not.



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

                Boolean to apply an inversion on the TE signal that triggers the MIPI DBI controller.



         * - ``dma-prefetch``
           - ``string``
           - .. code-block:: none

                Host controller will wait for at least the specified number of bytes before triggering
                a single frame update. The prefetch mechanism should be enabled when frame buffer(s)
                is stored into external storage mediums, e.g. PSRAM, that introduce comparable delays.
                In such a case it might case that the controller runs into underrun conditions which
                results in correpting the whole frame update. It's user's responsibility to ensure that
                the selected value does not exceed frame's total size as otherwise the controller will
                not be able to trigger the frame update.



             Legal values: ``'no-prefetch'``, ``'prefetch-44-bytes'``, ``'prefetch-84-bytes'``, ``'prefetch-116-bytes'``, ``'prefetch-108-bytes'``

         * - ``spi-dev``
           - ``phandle``
           - .. code-block:: none

                SPI bus to use for display read operations. When this property is present, MIPI DBI read
                operations will be exhibited by the driver. This is because, the LCDC IP block does not
                support read functionality, natively.
