            Bug ID: 218526
           Summary: Unable to achieve 240hz on usb4 docking station
           Product: Drivers
           Version: 2.5
          Hardware: AMD
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: USB
          Assignee: drivers_usb@kernel-bugs.kernel.org
          Reporter: samworlds123@gmail.com
        Regression: No

Kernel version used: 6.7.5

Using a display1.2 port to display1.4 port on the dock I'm not able to get
240hz on linux I max out at 165hz

On windows with the same dock and montior I get 240hz 

I've tested 3 wayland compositors which all had the same results.
