Ah, I wasn't aware that the same wakeup mechanism is used in runtime suspend.
In how far is runtime PM actually supported/used by this driver? The device is set 'active' in _probe(), and there are no other pm_runtime_* calls, except in dwc3_qcom_remove() and qcom_dwc3_resume_irq(). How does the device get from 'active' into 'suspended'?
