thunderbolt: Update Kconfig entries to USB4 Since the driver now supports USB4 which is the standard going forward, update the Kconfig entry to mention this and rename the entry from CONFIG_THUNDERBOLT to CONFIG_USB4 instead to help people to find the correct option if they want to enable USB4. Also do the same for Thunderbolt network driver. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Cc: David S.

thunderbolt: Add support for Intel Ice Lake The Thunderbolt controller is integrated into the Ice Lake CPU itself and requires special flows to power it on and off using force power bit in NHI VSEC registers. Runtime PM (RTD3) and Sx flows also differ from the discrete solutions. Now the firmware notifies the driver whether RTD3 entry or exit are possible. The driver is responsible of sending Go2Sx command through link controller mailbox when system enters Sx states (suspend-to-mem/disk). Rest of the ICM firwmare flows follow Titan Ridge.

thunderbolt: Add support for Time Management Unit Time Management Unit (TMU) is included in each USB4 router. It is used to synchronize time across the USB4 fabric. By default when USB4 router is plugged to the domain, its TMU is turned off. This differs from Thunderbolt (1, 2 and 3) devices whose TMU is by default configured to bi-directional HiFi mode. Since time synchronization is needed for proper Display Port tunneling this means we need to configure the TMU on USB4 compliant devices. The USB4 spec allows some flexibility on how the TMU can be configured. This makes it possible to enable link power management states (CLx) in certain topologies, where for example DP tunneling is not used. TMU can also be re-configured dynamicaly depending on types of tunnels created over the USB4 fabric. In this patch we simply configure the TMU to be in bi-directional HiFi mode. This way we can tunnel any kind of traffic without need to perform complex steps to re-configure the domain dynamically. We can add more fine-grained TMU configuration later on when we start enabling CLx states.
