From de4620391786513a6971029b61663563c4b7b961 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Thu, 2 Apr 2020 14:50:52 +0300 Subject: thunderbolt: Configure link after lane bonding is enabled During testing it was noticed that the link is not properly restored after the domain exits sleep if the link configured bits are set before lane bonding is enabled. The USB4 spec does not say in which order these need to be set but setting link configured afterwards makes the link restoration work so we do that instead.
