Details

resets

phandle-array

Reset information

This property is required.

dma-buffer-size

int

Size of DMA buffer in bytes

This property is required.

disallow-iso-in-out-same-number

boolean

Some soc series don't allow Isochronous IN/OUT endpoints to be assigned the same numbers,
for example, 0x82 (for Isochronous IN) and 0x02 (for Isochronous OUT) are disallowed.

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'

phandle-array

Control VBUS via GPIO pin.

reset-names

string-array

Name of each reset
