Merge tag 'tty-5.2-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/serial driver patches for 5.2-rc1.
It's really pretty small, not much happening in this portion of the kernel at the moment. When the "highlight" is the movement of the documentation from .txt to .rst files, it's a good merge window.
There's a number of small fixes and updates over the various serial drivers, and a new "tty null" driver for those embedded systems that like to make things even smaller and not break things.
All of these have been in linux-next for a while with no reported issues"

tty: serial: add driver for the SiFive UART
Add a serial driver for the SiFive UART, found on SiFive FU540 devices (among others).
The underlying serial IP block is relatively basic, and currently does not support serial break detection. Further information on the IP block can be found in the documentation and Chisel sources:
https://static.dev.sifive.com/FU540-C000-v1.0.pdf
https://github.com/sifive/sifive-blocks/tree/master/src/main/scala/devices/uart
This driver was written in collaboration with Wesley Terpstra <wesley@sifive.com>.
Tested on a SiFive HiFive Unleashed A00 board, using BBL and the open- source FSBL (using a DT file based on what's targeted for mainline).
This revision incorporates changes based on comments by Julia Lawall <julia.lawall@lip6.fr>, Emil Renner Berthing <kernel@esmil.dk>, and Andreas Schwab <schwab@suse.de>. Thanks also to Andreas for testing the driver with his userspace and reporting a bug with the set_termios implementation.
