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 drivers/thunderbolt/lc.c | 110 ++++++++++++++++++++++++++++++++++ drivers/thunderbolt/switch.c | 71 +++++++++++++++++++++- drivers/thunderbolt/tb.c | 11 ++++ drivers/thunderbolt/tb.h | 8 +++ drivers/thunderbolt/tb_regs.h | 9 +++ drivers/thunderbolt/tunnel.c | 10 ++++ 6 files changed, 218 insertions(+), 1 deletion(-)
