I ran v8 on a Lenovo Legion Tab Y700 Gen 5 (Kaanapali, M31 eUSB2 PHY),
v7.3-rc4 plus board patches. Host mode, wakeup enabled, s2idle:

 - hub with a FS keyboard behind it: no early wakeup in 10 RTC-timed
   cycles, and a key press wakes the system (dm_hs_phy_irq). Without
   the series it woke up right after entering suspend (dp_hs_phy_irq).
 - FS keyboard directly on the port: a key press wakes the system.
 - unplugging the hub during suspend wakes the system.
 - wakeup disabled: no change from before.
 - low speed: not tested, I have no LS device.

Only the m31 and dwc3-qcom parts were exercised; the snps-eusb2 change
was only built.
