Vendor: STMicroelectronics

Description

STM32 OTGHS controller

Properties

Node specific properties

Base 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 a shared FIFO size.

This property is required.

phys

phandle

 
PHY provider specifier

pinctrl-0

phandles

 
Pin configuration for USB OTG HS signals (DM/DP/SOF/ID/VBUS and
ULPI_DIR/ULPI_STP/ULPI_NXT/ULPI_D[0-7]).
We expect that the phandles will reference pinctrl nodes.

For example:
   <&usb_otg_hs_dm_pa11 &usb_otg_hs_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-otghs” compatible.

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
