Merge tag 'usb-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB/Thunderbolt/PHY driver updates from Greg KH:
 "Here is the big USB and Thunderbolt and PHY driver updates for
  5.6-rc1.

  With the advent of USB4, "Thunderbolt" has really become USB4, so the
  renaming of the Kconfig option and starting to share subsystem code
  has begun, hence both subsystems coming in through the same tree here.

  PHY driver updates also touched USB drivers, so that is coming in
  through here as well.

  Major stuff included in here are:
   - USB 4 initial support added (i.e. Thunderbolt)
   - musb driver updates
   - USB gadget driver updates
   - PHY driver updates
   - USB PHY driver updates
   - lots of USB serial stuff fixed up
   - USB typec updates
   - USB-IP fixes
   - lots of other smaller USB driver updates

  All of these have been in linux-next for a while now (the usb-serial
  tree is already tested in linux-next on its own before merged into
  here), with no reported issues"

[ Removed an incorrect compile test enablement for PHY_EXYNOS5250_SATA
  that causes configuration warnings    - Linus ]
