Merge tag 'tty-6.8-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 and serial driver changes for 6.8-rc1.

  As usual, Jiri has a bunch of refactoring and cleanups for the tty
  core and drivers in here, along with the usual set of rs485 updates
  (someday this might work properly...)

  Along with those, in here are changes for:

   - sc16is7xx serial driver updates

   - platform driver removal api updates

   - amba-pl011 driver updates

   - tty driver binding updates

   - other small tty/serial driver updates and changes

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