Base properties

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	Horizontal synchronization pulse duration, in pixels This property is required.
vsync-duration	int	Vertical synchronization pulse duration, in lines This property is required.
hbp-duration	int	Horizontal back-porch duration, in pixels This property is required.
vbp-duration	int	Vertical back-porch duration, in lines This property is required.
hfp-duration	int	Horizontal front porch duration, in pixels This property is required.
vfp-duration	int	Vertical front porch duration, in lines This property is required.
def-back-color-red	int	Default display background color - red
def-back-color-green	int	Default display background color - green
def-back-color-blue	int	Default display background color - blue
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.
pinctrl-1	phandles	Pin configuration/s for the second state. See pinctrl-0.
pinctrl-2	phandles	Pin configuration/s for the third state. See pinctrl-0.
pinctrl-3	phandles	Pin configuration/s for the fourth state. See pinctrl-0.
pinctrl-4	phandles	Pin configuration/s for the fifth state. See pinctrl-0.
pinctrl-names	string-array	Names for the provided states. The number of names needs to match the number of states.

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 “st,stm32-ltdc” compatible.

Name	Type	Details
clocks	phandle-array	Clock gate information This property is required.
interrupts	array	interrupts for device This property is required. See Important properties for more information.
label	string	Human readable string describing the device (used as device_get_binding() argument) This property is required. See Important properties for more information.
status	string	indicates the operational status of a device Legal values: 'ok', 'okay', 'disabled', 'reserved', 'fail', 'fail-sss' See Important properties for more information.
compatible	string-array	compatible strings This property is required. See Important properties for more information.
reg	array	register space See Important properties for more information.
reg-names	string-array	name of each register space
interrupts-extended	compound	extended interrupt specifier for device
interrupt-names	string-array	name of each interrupt
interrupt-parent	phandle	phandle to interrupt controller node
clock-names	string-array	name of each clock
#address-cells	int	number of address cells in reg property
#size-cells	int	number of size cells in reg property
dmas	phandle-array	DMA channels specifiers
dma-names	string-array	Provided names of DMA channel specifiers
io-channels	phandle-array	IO channels specifiers
io-channel-names	string-array	Provided names of IO channel specifiers
mboxes	phandle-array	mailbox / IPM channels specifiers
mbox-names	string-array	Provided names of mailbox / IPM channel specifiers
wakeup-source	boolean	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.
power-domain	phandle	Power domain the device belongs to. The device will be notified when the power domain it belongs to is either suspended or resumed.
