Properties

Properties not inherited from the base binding file.

Name

Type

Details

pp-height-bits

int

 
Number of bits used for the height parameters

This property is required.

pp-width-bits

int

 
Number of bits used for the width parameters

This property is required.

gdv

uint8-array

 
Gate driving voltage values

sdv

uint8-array

 
Source driving voltage values

vcom

int

 
VCOM voltage

border-waveform

int

 
Border waveform

softstart

uint8-array

 
Booster soft start values

orientation-flipped

boolean

 
Last column address is mapped to first segment

reset-gpios

phandle-array

 
RESET pin.
The RESET pin of SSD16XX is active low. If connected directly the MCU pin should be configured as active low.

This property is required.

dc-gpios

phandle-array

 
DC pin.
The DC pin of SSD16XX is active low (transmission command byte). If connected directly the MCU pin should be configured as active low.

This property is required.

busy-gpios

phandle-array

 
BUSY pin.
The BUSY pin of SSD16XX is active high. If connected directly the MCU pin should be configured as active high.

This property is required.

lut-initial

uint8-array

 
Initial LUT used when initializing the device and performing
clearing the screen using a full refresh operation. The
default LUT will be loaded from OTP if this property isn't
defined.

lut-default

uint8-array

tssv

int

 
Temperature Sensor Selection Value
Display controller can have integrated temperature sensor or an external temperature sensor is connected to the controller. The value selects which sensor should be used.

dummy-line

int

 
Dummy line period override.

gate-line-width

int

 
Gate line width override.

spi-max-frequency

int

 
Maximum clock frequency of device's SPI interface in Hz

This property is required.

duplex

int

 
Duplex mode, full or half. By default it's always full duplex thus 0
as this is, by far, the most common mode.
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

Legal values: 0, 2048

frame-format

int

 
Motorola or TI frame format. By default it's always Motorola's,
thus 0 as this is, by far, the most common format.
Use the macros not the actual enum value, here is the concordance
list (see dt-bindings/spi/spi.h)
  0     SPI_FRAME_FORMAT_MOTOROLA
  32768 SPI_FRAME_FORMAT_TI

Legal values: 0, 32768

supply-gpios

phandle-array

 
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

 
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

int

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

This property is required.

width

int

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

This property is required.
