Hi all, This series adds initial support for the next USB4 version (USB4 v2) and the Intel Barlow Ridge discrete controller. This includes support for the 80G symmetric link, the necessary configuration needed to bring up the router in v2 mode, adaptive TMU, PCIe extended encapsulation, and CL2 low power link state. We will be sending the rest of the USB4 v2 support, including asymmetric 128/80G link support later on once this one has settled. These are based on thunderbolt.git/next. The previous version of the series can be found: https://lore.kernel.org/linux-usb/20230531090645.5573-1-mika.westerberg@xxxxxxxxxxxxxxx/ Changes from v1: * Make tb_switch_is_usb4() use usb4_switch_version() as well * Set TMU mode off by default in tmu_mode_init() * Log TMU mode change only if it is actually changed in tb_switch_tmu_configure().
