Merge tag 'tty-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty and serial driver updates from Greg KH:
 "Here is the big set of tty and serial driver updates for 5.19-rc1.

  Lots of tiny cleanups in here, the major stuff is:

   - termbit cleanups and unification by Ilpo. A much needed change that
     goes a long way to making things simpler for all of the different
     arches

   - tty documentation cleanups and movements to their own place in the
     documentation tree

   - old tty driver cleanups and fixes from Jiri to bring some existing
     drivers into the modern world

   - RS485 cleanups and unifications to make it easier for individual
     drivers to support this mode instead of having to duplicate logic
     in each driver

   - Lots of 8250 driver updates and additions

   - new device id additions

   - n_gsm continued fixes and cleanups

   - other minor serial driver updates and cleanups

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