Merge tag 'thunderbolt-for-v6.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/westeri/thunderbolt into usb-linus
Mika writes: thunderbolt: Fixes for v6.7-rc3 This includes following USB4/Thunderbolt fixes for v6.7-rc3: - Fix a lane bonding issue on ASMedia USB4 device - Send uevents when link is switched to asymmetric or symmetric - Only add device router DP IN adapters to the head of resource list to avoid issues during system resume. All these have been in linux-next with no reported issues. * tag 'thunderbolt-for-v6.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/westeri/thunderbolt: (1451 commits) thunderbolt: Only add device router DP IN to the head of the DP resource list thunderbolt: Send uevent after asymmetric/symmetric switch thunderbolt: Set lane bonding bit only for downstream port
