* - Name
- Type
- Details
* - ``frmctr1``
- ``uint8-array``
- .. code-block:: none
Frame rate control (in normal mode / full colors) (FRMCTR1) register value.
Default value: ``[176, 17]``
* - ``disctrl``
- ``uint8-array``
- .. code-block:: none
Display function control (DISCTRL) register value. Note that changing default SS bit value (0) may interfere with display rotation.
Default value: ``[2, 2, 59]``
* - ``pwctrl1``
- ``uint8-array``

Power control 1 (PWCTRL1) register values.
Default value: ``[14, 14]``
* - ``pwctrl2``
- ``uint8-array``
- .. code-block:: none
Power control 2 (PWCTRL2) register values.
Default value: ``[67]``
* - ``vmctrl``
- ``uint8-array``
- .. code-block:: none
VCOM control (VMCTRL) register values.
Default value: ``[0, 64, 0, 64]``
* - ``pgamctrl``
- ``uint8-array``
- .. code-block:: none
Positive gamma correction (PGAMCTRL) register values.
Default value: ``[15, 31, 28, 11, 14, 9, 72, 153, 56, 10, 20, 6, 17, 9, 0]``
* - ``ngamctrl``
- ``uint8-array``
- .. code-block:: none
Negative gamma correction (NGAMCTRL) register values.
Default value: ``[15, 54, 46, 9, 10, 4, 70, 102, 55, 6, 16, 4, 36, 32, 0]``
* - ``reset-gpios``
- ``phandle-array``
- .. code-block:: none
RESET pin.
The RESET pin of ILI9340 is active low. If connected directly the MCU pin should be configured as active low.
* - ``cmd-data-gpios``
- ``phandle-array``
- .. code-block:: none
D/CX pin.
The D/CX pin of ILI9340 is active low (transmission command byte). If connected directly the MCU pin should be configured as active low.
This property is **required**.
* - ``pixel-format``
- ``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.
Legal values: ``0``, ``90``, ``180``, ``270``
* - ``display-inversion``
- ``boolean``
- .. code-block:: none
Display inversion mode. Every bit is inverted from the frame memory to the display.
* - ``spi-max-frequency``
- ``int``
- .. code-block:: none
Maximum clock frequency of device's SPI interface in Hz
This property is **required**.
* - ``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.
.. 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 "ilitek,ili9488" compatible.

This property is **required**.
See :ref:`zephyr:dt-important-props` for more information.
* - ``status``
- ``string``
- .. code-block:: none

* - ``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.
