solomon,ssd16xxfb (on spi bus)

Vendor: Solomon Systech Limited

Description

SSD16XX 250x150 EPD display controller

Properties

Properties not inherited from the base binding file.

Name

Type

Details

height

int

Height in pixel of the panel driven by the controller

This property is required.

width

int

Width in pixel of the panel driven by the controller

This property is required.

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

This property is required.

sdv

uint8-array

Source driving voltage values

This property is required.

vcom

int

VCOM voltage

This property is required.

border-waveform

int

Border waveform

This property is required.

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

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.

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

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.
