USB4 spec says that for TBT3 compatible device routers the connection manager needs to set SLI (Start Lane Initialization) to get the lanes that were not connected back to functional state after sleep. Same needs to be done if the link was XDomain. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Acked-by: Yehezkel Bernat <YehezkelShB@gmail.com>
