Currently we notify PM core about occurred wakes after any resume. This

PM core about occurred wakes only after resume from system sleep. Also,
if the wake occurred in USB4 router upstream port, we don't notify the

unexpected autowake (e.g. if /sys/power/wakeup_count is used).

thunderbolt: Reset topology created by the boot firmware
commit 59a54c5f3dbde00b8ad30aef27fe35b1fe07bf5c upstream.
Boot firmware (typically BIOS) might have created tunnels of its own.
The tunnel configuration that it does might be sub-optimal. For instance
it may only support HBR2 monitors so the DisplayPort tunnels it created
may limit Linux graphics drivers. In addition there is an issue on some
AMD based systems where the BIOS does not allocate enough PCIe resources
for future topology extension. By resetting the USB4 topology the PCIe
links will be reset as well allowing Linux to re-allocate.
This aligns the behavior with Windows Connection Manager.
We already issued host router reset for USB4 v2 routers, now extend it
to USB4 v1 routers as well. For pre-USB4 (that's Apple systems) we leave
it as is and continue to discover the existing tunnels.

thunderbolt: Keep the domain powered when USB4 port is in redrive mode
[ Upstream commit a75e0684efe567ae5f6a8e91a8360c4c1773cf3a ]
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).

thunderbolt: Keep the domain powered when USB4 port is in redrive mode
[ Upstream commit a75e0684efe567ae5f6a8e91a8360c4c1773cf3a ]
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).

thunderbolt: Add support for enhanced uni-directional TMU mode
This is new TMU mode introduced with the USB4 v2. This mode is simpler
than the existing ones and allows all CL states as well. Enable this for
all links where both side routers are v2 and keep the existing
functionality for the v1 and earlier links.
Currently only support the MedRes rate. We can add the HiFi rate later
too if it turns out to be useful.
