Merge tag 'tty-6.16-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 6.16-rc1.

  A little more churn than normal in this portion of the kernel for this
  development cycle, Jiri and Nicholas were busy with cleanups and
  reviews and fixes for the vt unicode handling logic which composed
  most of the overall work in here.

  Major changes are:

   - vt unicode changes/reverts/changes from Nicholas. This should help
     out a lot with screen readers and others that rely on vt console
     support

   - lock guard additions to the core tty/serial code to clean up lots
     of error handling logic

   - 8250 driver updates and fixes

   - device tree conversions to yaml

   - sh-sci driver updates

   - other small cleanups and updates for serial drivers and tty core
     portions

  All of these have been in linux-next for 2 weeks with no reported issues"
