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.

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.
`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
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information. This property is deprecated.
`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.
