STM32 OTGHS controller

Properties

Node specific properties

Deprecated node specific properties

Base properties

Properties not inherited from the base binding file.

Name	Type	Details
pinctrl-0	phandles	Pin configuration/s for the first state. Content is specific to the selected pin controller driver implementation. This property is required.
pinctrl-names	string-array	Names for the provided states. The number of names needs to match the number of states. This property is required.
ram-size	int	Size of USB dedicated RAM. STM32 SOC's reference manual defines a shared FIFO size. This property is required.
phys	phandle	PHY provider specifier
num-bidir-endpoints	int	Number of bi-directional endpoints supported by hardware (including EP0) This property is required.
num-in-endpoints	int	Number of IN endpoints supported by hardware (including EP0 IN)
num-out-endpoints	int	Number of OUT endpoints supported by hardware (including EP0 OUT)
maximum-speed	string	Configures USB controllers to work up to a specific speed. Valid arguments are "super-speed", "high-speed", "full-speed" and "low-speed". If this is not passed via DT, USB controllers should use their maximum hardware capability. Legal values: 'low-speed', 'full-speed', 'high-speed', 'super-speed'
vbus-gpios	phandle-array	Control VBUS via GPIO pin.
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.

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-otghs” compatible.

Name	Type	Details
reg	array	register space This property is required. See Important properties for more information.
interrupts	array	interrupts for device This property is required. See Important properties for more information.
clocks	phandle-array	Clock gate information This property is required.
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-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.
