USB/PHY patches for 5.2-rc1

Browse source 
Here is the big set of USB and PHY driver patches for 5.2-rc1
 
 There is the usual set of:
 	- USB gadget updates
 	- PHY driver updates and additions
 	- USB serial driver updates and fixes
 	- typec updates and new chips supported
 	- mtu3 driver updates
 	- xhci driver updates
 	- other tiny driver updates
 
 Nothing really interesting, just constant forward progress.
 
 All of these have been in linux-next for a while with no reported
 issues.  The usb-gadget and usb-serial trees were merged a bit "late",
 but both of them had been in linux-next before they got merged here last
 Friday.
