Mika Westerberg f692c547e3 thunderbolt: Keep the domain powered when USB4 port is in redrive mode ... [ Upstream commit a75e0684ef ] If a DiplayPort cable is directly connected to the host routers USB4 port, there is no tunnel involved but the port is in "redrive" mode meaning that it is re-driving the DisplayPort signals from its DisplayPort source. In this case we need to keep the domain powered on otherwise once the domain enters D3cold the connected monitor blanks too. Since this happens only on Intel Barlow Ridge add a quirk that takes runtime PM reference if we detect that the USB4 port entered redrive mode (and release it once it exits the mode).
