Currently the handler misses this and tries to allocate 0 Mb/s that then makes the graphics side to think the request failed. Fix this by properly handling the enablement notification.

This is referred as "bandwidth allocation mode" in the spec. The connection manager uses DP IN adapters registers to communicate with the graphics, and also gets notifications from these adapters when the graphics wants to change the bandwidth allocation. Both the connection manager and the graphics driver needs to support this. We check if the DP IN adapter supports this and if it does enable it before establishing a DP tunnel. Then we react on DP_BW notifications coming from the DP IN adapter and update the bandwidth allocation accordingly (within the maximum common capabilities the DP IN/OUT support).

This leads to hang because neither can proceed. Fix this by runtime resuming USB4 ports in tb_scan_port() instead. This makes sure the ports are runtime PM active when retimers are added under it while avoiding the reported hang as well.

Nothing major in here, lots of little things with new devices supported and updates for a few drivers. Highlights include: - thunderbolt/USB4 devices supported a bit better than before, and some new ids to enable new hardware devices - USB gadget uvc updates for newer video formats and better v4l integration (the v4l portions were acked by those maintainers) - typec updates for tiny issues and more typec drivers for new chips. - xhci tiny updates for minor issues - big usb-serial ftdi_sio driver update to handle new devices better - lots of tiny dwc3 fixes and updates for the IP block that is showing up everywhere these days - dts updates for new devices being supported - other tiny janitorial and cleanups fixes for lots of different USB drivers.

However, this is not necessary for USB4 host routers as this functionality is part of router operations that the router implements if it wants to support this.
