Merge tag 'tty-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty / serial driver updates from Greg KH:
 "Here is the "big" set of tty/serial driver updates for 6.12-rc1.

  Nothing major in here, just nice forward progress in the slow cleanup
  of the serial apis, and lots of other driver updates and fixes.

  Included in here are:

   - serial api updates from Jiri to make things more uniform and sane

   - 8250_platform driver cleanups

   - samsung serial driver fixes and updates

   - qcom-geni serial driver fixes from Johan for the bizarre UART
     engine that that chip seems to have. Hopefully it's in a better
     state now, but hardware designers still seem to come up with more
     ways to make broken UARTS 40+ years after this all should have
     finished.

   - sc16is7xx driver updates

   - omap 8250 driver updates

   - 8250_bcm2835aux driver updates

   - a few new serial driver bindings added

   - other serial minor driver updates

  All of these have been in linux-next for a long time with no reported
  problems"
