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.
`resets`	`phandle-array`	Reset information This property is required.
`pinctrl-0`	`phandles`	Provide a pin configuration for using parallel pixel output. In combination with DSI HOST the pin configuration is not necessary due to dedicated (MIPI D-PHY) pins.
`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
`window0-x0`	`int`	First pixel in x direction on layer 0. Defaults to 0.
`window0-x1`	`int`	Last pixel in x direction on layer 0. Defaults to width.
`window0-y0`	`int`	First pixel in y direction on layer 0. Defaults to 0.
`window0-y1`	`int`	Last pixel in y direction on layer 0. Defaults to height.
`display-controller`	`phandle`	Phandle of the display's controller. When provided, it's used to forward some of the configuration calls (e.g. blanking on/off) sent to LTDC device.
`pixel-format`	`int`	Initial Pixel format for panel attached to this controller. See dt-bindings/display/panel.h for a list This property is required.
`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.
`reset-names`	`string-array`	Name of each reset

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
`power-domains`	`phandle-array`	Power domain specifiers
`power-domain-names`	`string-array`	Provided names of power domain specifiers
`#power-domain-cells`	`int`	Number of cells in power-domains property
`zephyr,deferred-init`	`boolean`	Do not initialize device automatically on boot. Device should be manually initialized using device_init().
`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.
`zephyr,pm-device-runtime-auto`	`boolean`	Automatically configure the device for runtime power management after the init function runs.
`zephyr,disabling-power-states`	`phandles`	List of power states that will disable this device power.
