Merge tag 'tty-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty/serial driver updates from Greg KH:
 "Here is the big set of tty and serial driver patches for 4.17-rc1

  Not all that big really, most are just small fixes and additions to
  existing drivers. There's a bunch of work on the imx serial driver
  recently for some reason, and a new embedded serial driver added as
  well.

  Full details are in the shortlog.

  All of these have been in the linux-next tree for a while with no
  reported issues"
