Pull tty/serial driver updates from Greg KH:
 "Here are the big set of tty and serial driver changes for 5.18-rc1.

  Nothing major, some more good cleanups from Jiri and 2 new serial
  drivers. Highlights include:

   - termbits cleanups

   - export symbol cleanups and other core cleanups from Jiri Slaby

   - new sunplus and mvebu uart drivers (amazing that people are still
     creating new uarts...)

   - samsung serial driver cleanups

   - ldisc 29 is now "reserved" for experimental/development line
     disciplines

   - lots of other tiny fixes and cleanups to serial drivers and
     bindings

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

      List of parent clocks suitable for UART from following set:
        "TBG-A-P", "TBG-B-P", "TBG-A-S", "TBG-B-S", "xtal"
      UART clock can use one from this set and when more are provided
      then kernel would choose and configure the most suitable one.
      It is suggest to specify at least one TBG clock to achieve
      baudrates above 230400 and also to specify clock which bootloader
      used for UART (most probably xtal) for smooth boot log on UART.
