Merge tag 'tty-6.1-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 updates for 6.1-rc1.

  Lots of cleanups in here, no real new functionality this time around,
  with the diffstat being that we removed more lines than we added!

  Included in here are:

   - termios unification cleanups from Al Viro, it's nice to finally get
     this work done

   - tty serial transmit cleanups in various drivers in preparation for
     more cleanup and unification in future releases (that work was not
     ready for this release)

   - n_gsm fixes and updates

   - ktermios cleanups and code reductions

   - dt bindings json conversions and updates for new devices

   - some serial driver updates for new devices

   - lots of other tiny cleanups and janitorial stuff. Full details in
     the shortlog.

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