Name

Type

Details

reset-gpios

phandle-array

RESET pin.
The RESET pin of ST7789V is active low. If connected directly the MCU pin should be configured as active low.

This property is required.

cmd-data-gpios

phandle-array

D/CX pin.
The D/CX pin of ST7789V is active low (transmission command byte). If connected directly the MCU pin should be configured as active low.

This property is required.

height

int

Height in pixels of the panel driven by the controller

This property is required.

width

int

Width in pixels of the panel driven by the controller

This property is required.

x-offset

int

The column offset in pixels of the LCD to the controller memory

This property is required.

y-offset

int

The row offset in pixels of the LCD to the controller memory

This property is required.

vcom

int

VCOM Setting

This property is required.

gctrl

int

Gate Control

This property is required.

vrhs

int

VRH Setting

vdvs

int

VDV Setting

mdac

int

Memory Data Access Control

This property is required.

lcm

int

LCM Setting

This property is required.

colmod

int

Interface Pixel Format

This property is required.

gamma

int

Gamma Setting

This property is required.

porch-param

uint8-array

Porch Setting

This property is required.

cmd2en-param

uint8-array

Command 2 Enable Parameter

This property is required.

pwctrl1-param

uint8-array

Power Control 1 Parameter

This property is required.

pvgam-param

uint8-array

Positive Voltage Gamma Control Parameter

This property is required.

nvgam-param

uint8-array

Negative Voltage Gamma Control Parameter

This property is required.

ram-param

uint8-array

RAM Control Parameter

This property is required.

rgb-param

uint8-array

RGB Interface Control Parameter

This property is required.

spi-max-frequency

int

Maximum clock frequency of device's SPI interface in Hz

This property is required.

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.
