Merge tag 'usb-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB and PHY updates from Greg KH:
"Here is the big USB pull request for 4.18-rc1.
Lots of stuff here, the highlights are:
- phy driver updates and new additions
- usual set of xhci driver updates
- normal set of musb updates
- gadget driver updates and new controllers
- typec work, it's getting closer to getting fully out of the staging
portion of the tree.
- lots of minor cleanups and bugfixes.
All of these have been in linux-next for a while with no reported
issues"
