Properties
Properties not inherited from the base binding file.
Name |
Type |
Details |
|---|---|---|
|
|
Gamma set (GAMSET) register value.
Default value: |
|
|
Frame rate control (in normal mode / full colors) (FRMCTR1) register value.
Default value: |
|
|
Display function control (DISCTRL) register value. Note that changing default SS bit value (0) may interfere with display rotation.
Default value: |
|
|
Power control 1 (PWCTRL1) register values.
Default value: |
|
|
Power control 2 (PWCTRL2) register values.
Default value: |
|
|
VCOM control 1 (VMCTRL1) register values.
Default value: |
|
|
VCOM control 2 (VMCTRL2) register values.
Default value: |
|
|
Positive gamma correction (PGAMCTRL) register values.
Default value: |
|
|
Negative gamma correction (NGAMCTRL) register values.
Default value: |
|
|
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: |
|
|
Display rotation (CW) in degrees. If not defined, rotation is off by default.
Legal values: |
|
|
Display inversion mode. Every bit is inverted from the frame memory to the display.
|
|
|
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
|
|
|
SPI clock polarity which indicates the clock idle state.
If it is used, the clock idle state is logic high; otherwise, low.
|
|
|
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.
|
|
|
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.
|
|
|
Maximum clock frequency of device's MIPI interface in Hz
|
|
|
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: |
|
|
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.
|
|
|
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.
|
|
|
Height of the panel driven by the controller, with the units in pixels.
This property is required. |
|
|
Width of the panel driven by the controller, with the units in pixels.
This property is required. |
Deprecated properties not inherited from the base binding file.
(None)
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,ili9340” compatible.

|
Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
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.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
|
|
|
List of power states that will disable this device power.
