Hi all,

The first two patches implement flows that are needed to bring up the
internal xHCI controller when there is USB device connected to the
downstream Thunderbolt port of the the router. The last patch disables
LTTPR (LT-tunable PHY Repeater, DisplayPort term) when Titan Ridge device
router is connected to avoid tunneling issues.

Mika Westerberg (3):
  thunderbolt: Add missing device ID to tb_switch_is_alpine_ridge()
  thunderbolt: Add internal xHCI connect flows for Thunderbolt 3 devices
  thunderbolt: Disable LTTPR on Intel Titan Ridge

Fixed the typo pointed out by Lukas and applied to thunderbolt.git/next.
