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" * tag 'usb-5.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (145 commits) Revert "usb: gadget: storage: Remove warning message" Revert "dt-bindings: add binding for USBSS-DRD controller."
