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"

vt: move UCS tables to the "shipped" form

Use the "shipped" mechanism to copy pre-generated tables to the build
tree by default. If GENERATE_UCS_TABLES=1 then they are generated at
build time instead. If GENERATE_UCS_TABLES=2 then
gen_ucs_recompose_table.py is invoked with --full.

vt: update gen_ucs_width_table.py to make tables more space efficient

Split table ranges into BMP (16-bit) and non-BMP (above 16-bit).
This reduces the corresponding text size by 20-25%.

vt: introduce gen_ucs_width_table.py to create ucs_width_table.h

The table in ucs.c is terribly out of date and incomplete. We also need a
second table to store zero-width code points. Properly maintaining those
tables manually is impossible. So here's a script to generate them.
