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"
