Merge tag 'tty-6.3-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 serial and tty driver updates for 6.3-rc1.

  Once again, Jiri and Ilpo have done a number of core vt and tty/serial
  layer cleanups that were much needed and appreciated. Other than that,
  it's just a bunch of little tty/serial driver updates:

   - qcom-geni-serial driver updates

   - liteuart driver updates

   - hvcs driver cleanups

   - n_gsm updates and additions for new features

   - more 8250 device support added

   - fpga/dfl update and additions

   - imx serial driver updates

   - fsl_lpuart updates

   - other tiny fixes and updates for serial drivers

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