Hi Greg,
Please pull Thunderbolt changes for v5.5 merge window. I needed to merge my fixes branch here because there is dependency between some of the commits. The fixes branch is already included in your char-misc-linus branch.
Thanks!

thunderbolt: Do not start firmware unless asked by the user (2019-11-02 12:13:31 +0300)
---------------------------------------------------------------- thunderbolt: Changes for v5.5 merge window
This adds Thunderbolt 3 support for the software connection manager. It is currently only used in Apple systems. Previously the driver started the firmware connection manager on those but it is not necessary anymore with these patches (we still leave user an option to start the firmware in case there are problems with the software connection manager).
This includes:
- Expose 'generation' attribute under each device in sysfs - Converting register names to follow the USB4 spec. - Lane bonding support - Expose link speed and width in sysfs - Display Port handshake needed for Titan Ridge devices - Display Port pairing and resource management - Display Port bandwidth management
