Re: [PATCH v2] dwc2: Delay resume until device connection is stable

[Jason Sun]

Hi Greg,

Thanks for the feedback.

At the moment I only have access to this board on a 5.15-based BSP, so I can only run-time test on v5.15.140. I don't currently have a working mainline (v6.x) boot chain for this hardware.

The patch applies cleanly and builds on the current usb.git tree (v6.15-based, build-tested only). The change is based on reviewing the resume path around VBUS enable, which still proceeds after a fixed usleep_range(3000, 5000) delay and can observe an unstable CONNSTS window on our setup.

Please let me know if build-tested on usb.git is acceptable for now, or if you'd prefer the change to be conditional (e.g. via DT or a module parameter).

Thanks,
Jason Sun
