Merge tag 'usb-5.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB / PHY updates from Greg KH:
"Here is the big USB and PHY driver pull request for 5.3-rc1.
Lots of stuff here, all of which has been in linux-next for a while
with no reported issues. Nothing is earth-shattering, just constant
forward progress for more devices supported and cleanups and small
fixes:
- USB gadget driver updates and fixes
- new USB gadget driver for some hardware, followed by a quick revert
of those patches as they were not ready to be merged...
- PHY driver updates
- Lots of new driver additions and cleanups with a few fixes mixed
in"
