Pull USB/PHY driver updates from Greg KH:
"Here are the large set of USB and PHY driver updates for 5.8-rc1.
Nothing huge, just lots of little things:
- USB gadget fixes and additions all over the place
- new PHY drivers
- PHY driver fixes and updates
- XHCI driver updates
- musb driver updates
- more USB-serial driver ids added
- various USB quirks added
- thunderbolt minor updates and fixes
- typec updates and additions
All of these have been in linux-next for a while with no reported
issues"
