Subject: usb: dwc3: Update maximum_speed for SuperSpeedPlus
|
|
|
|
If the maximum_speed is not set, set it to a known value, either
|
|
SuperSpeed or SuperSpeedPlus based on the type of controller we are
|
|
using. If we are on DWC_usb31 controller, check the PHY interface to see
|
|
if it is capable of SuperSpeedPlus.
|
|
|
|
Also this check is moved after dwc3_core_init() so that we can check
|
|
dwc->revision.
