Properties

Node specific 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

Deprecated node specific properties

Deprecated properties not inherited from the base binding file.

(None)

Base properties

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.
