st,stm32-usb¶

Vendor: STMicroelectronics

Description¶

These nodes are “usb” bus nodes.

STM32 USB controller

Properties¶

Properties not inherited from the base binding file.

Name	Type	Details
`ram-size`	`int`	Size of USB dedicated RAM. STM32 SOC's reference manual defines USB packet SRAM size. This property is required.
`disconnect-gpios`	`phandle-array`	Some boards use a USB DISCONNECT pin to enable the pull-up resistor on USB Data Positive signal.
`phys`	`phandle`	PHY provider specifier
`enable-pin-remap`	`boolean`	For STM32F0 series SoCs on QFN28 and TSSOP20 packages enable PIN pair PA11/12 mapped instead of PA9/10 (e.g. stm32f070x6)
`pinctrl-0`	`phandles`	Pin configuration for USB signals (DM/DP/NOE). We expect that the phandles will reference pinctrl nodes. For example: <&usb_dm_pa11 &usb_dp_pa12>;
`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.

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-usb” 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
`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.
