I tried the host side on a Lenovo Legion Tab Y700 Gen 5 (SM8850,
dwc3-qcom), v7.3-rc4 plus board patches, s2idle with an RTC wakeup:
- host with wakeup disabled (USB 2.0 hub, USB 3 flash drive behind
it): "HS-PHY not in L2" on every suspend before, none with the
patch; the devices are still there after resume
- host with wakeup enabled: no message, the port does reach L2
- peripheral (connected to a PC): no message
