Merge tag 'tty-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty / serial updates from Greg KH:
 "Here is the "big" set of tty/serial driver patches for 5.15-rc1

  Nothing major in here at all, just some driver updates and more
  cleanups on old tty apis and code that needed it that includes:

   - tty.h cleanup of things that didn't belong in it

   - other tty cleanups by Jiri

   - driver cleanups

   - rs485 support added to amba-pl011 driver

   - dts updates

   - stm32 serial driver updates

   - other minor fixes and driver updates

  All have been in linux-next for a while with no reported problems"
