Description

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.
