Properties not inherited from the base binding file.

Name

Type

Details

disp-on-gpios

phandle-array

Display on/off GPIO pin.
Configure the GPIO polarity (active high/active low) according to LCD datasheet.

bl-ctrl-gpios

phandle-array

Backlight on/off GPIO pin.
Configure the GPIO polarity (active high/active low) according to LCD datasheet.

ext-sdram

phandle

External SDRAM in which frame buffer will be stored.
If not defined, internal RAM will be used.

pinctrl-0

phandles

Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.

This property is required.

hsync-pol

int

Horizontal synchronization pulse polarity.
If HSYNC is active low, use STM32_LTDC_HSPOL_ACTIVE_LOW,
otherwise use STM32_LTDC_HSPOL_ACTIVE_HIGH.

This property is required.

vsync-pol

int

Vertical synchronization pulse polarity.
If VSYNC is active low, use STM32_LTDC_VSPOL_ACTIVE_LOW,
otherwise use STM32_LTDC_VSPOL_ACTIVE_HIGH.

This property is required.

de-pol

int

Data enable pulse polarity.
If DE is active low, use STM32_LTDC_DEPOL_ACTIVE_LOW,
otherwise use STM32_LTDC_DEPOL_ACTIVE_HIGH.

This property is required.

pclk-pol

int

Pixel clock polarity.
If RGB data is sampled on falling edge of PCLK, use STM32_LTDC_PCPOL_ACTIVE_LOW,
otherwise use STM32_LTDC_PCPOL_ACTIVE_HIGH.

This property is required.

hsync-duration

int
