"Here is the big set of tty and serial driver changes for 6.8-rc1.

As usual, Jiri has a bunch of refactoring and cleanups for the tty
core and drivers in here, along with the usual set of rs485 updates
(someday this might work properly...)

Along with those, in here are changes for:

- sc16is7xx serial driver updates

- platform driver removal api updates

- amba-pl011 driver updates

- tty driver binding updates

- other small tty/serial driver updates and changes

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

"Here is the big set of tty and serial driver changes for 6.6-rc1.

Lots of cleanups in here this cycle, and some driver updates. Short
summary is:

- Jiri's continued work to make the tty code and apis be a bit more
sane with regards to modern kernel coding style and types

- cpm_uart driver updates

- n_gsm updates and fixes

- meson driver updates

- sc16is7xx driver updates

- 8250 driver updates for different hardware types

- qcom-geni driver fixes

- tegra serial driver change

- stm32 driver updates

- synclink_gt driver cleanups

- tty structure size reduction

All of these have been in linux-next this week with no reported
issues. The last bit of cleanups from Jiri and the tty structure size
reduction came in last week, a bit late but as they were just style
changes and size reductions, I figured they should get into this merge
cycle so that others can work on top of them with no merge conflicts"
