Hello linux-usb,
Dear Thunderbolt driver maintainers,

I just tried to swap my TB 4 setup with TB 5 hardware.
USB devices and power supply works as expected. Displayport does not.

Setup:
TB 5 Host (Lenovo P1 Gen8)
  -> TB 4 Dock (0108:2031 reports as "ThinkPad Thunderbolt 4 Dock")
    -> USB Devices, two 3840x2160, LAN attached
  -> TB 5 Dock (0108:234d reports as "ThinkPad Thunderbolt 5 Smart Dock 7500 - 40BA")
    -> nothing but power supply

Now I just move one of the dp cables from the TB 4 dock to the TB 5 dock and best thing I can get is a quick flicker
with a good signal but from then the monitor is black turning on and off continuously (seems to get a signal that collapses instantly).

I attached the dmesg debug log for this scenario.

This also happens if I use the TB 5 dock alone (with all USB stuff attached) but the behavior is way more inconsistent, with some monitors not coming up
at all or loosing signal after a few seconds.

I have no clue if this is the right list to report, I'm happy to report this to the drm subsystem if I'm wrong here :)

Best regards,
Frederik
