st,stm32-mipi-dsi

Note

An implementation of a driver matching this compatible is available in drivers/mipi_dsi/dsi_stm32.c.

Description

These nodes are “mipi-dsi” bus nodes.

STM32 MIPI DSI host

Properties

Properties not inherited from the base binding file.

Name	Type	Details
`resets`	`phandle-array`	Reset information This property is required.
`hs-active-high`	`boolean`	DSI host horizontal synchronization is active high.
`vs-active-high`	`boolean`	DSI host vertical synchronization is active high.
`de-active-high`	`boolean`	DSI host data enable is active high.
`loosely-packed`	`boolean`	Enable or disable loosely packed stream (needed only when using 18-bit configuration).
`largest-packet-size`	`int`	The size, in bytes, of the low power largest packet that can fit in a line during VSA, VBP, VFP and VACT regions
`bta-ack-disable`	`boolean`	Disable frame bus-turn-around acknowledge enable
`non-continuous`	`boolean`	DSI host enable non continuous clock.
`pll-ndiv`	`int`	DSI host dedicated PLL loop division factor. This property is required.
`pll-idf`	`int`	DSI host dedicated PLL input division factor. This property is required.
`pll-odf`	`int`	DSI HOST dedicated PLL output division factor. This property is required.
`active-errors`	`int`	Indicates which error interrupts will be enabled. This parameter can be any combination of DSI_Error_Data_Type and defaults to HAL_DSI_ERROR_NONE.
`lp-rx-filter`	`int`	Use Low-Power Reception Filter. Cutoff frequency of low-pass filter at the input of LPRX. Defaults to 0 which disables the filter.
`host-timeouts`	`array`	DSI HOST timeout parameters.
`phy-timings`	`array`	DSI HOST PHY timing parameters.
`test-pattern`	`int`	Show DSI host color bars, select color bar orientation 0 : Vertical color bars 1 : Horizontal color bars Legal values: `0`, `1`
`phy-clock`	`int`	MIPI PHY clock frequency. Should be set to ensure clock frequency is at least (pixel clock * bits per output pixel) / number of mipi data lanes
`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-mipi-dsi” compatible.

Name	Type	Details
`clocks`	`phandle-array`	Clock gate information This property is required.
`clock-names`	`string-array`	"dsiclk" DSI clock enable. "refclk" External crystal or oscillator clock. "pixelclk" LTDC pixel clock. "refclk" and "pixelclk" are only used to retrieve the frequency for timing calculation. This property is required.
`#address-cells`	`int`	number of address cells in reg property This property is required. Constant value: `1`
`#size-cells`	`int`	number of size cells in reg property This property is required.
`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`	`array`	interrupts for device See Important properties for more information.
`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.
`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.
