tty: Rework receive flow control char logic (2022-05-19 18:33:34 +0200)
----------------------------------------------------------------
TTY / Serial driver changes for 5.19-rc1
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.
