"Here is the big set of tty and serial driver changes for 6.0-rc1.

It was delayed from last week as I wanted to make sure the last commit
here got some good testing in linux-next and elsewhere as it seemed to
show up only late in testing for some reason.

Nothing major here, just lots of cleanups from Jiri and Ilpo to make
the tty core cleaner (Jiri) and the rs485 code simpler to use (Ilpo).

Also included in here is the obligatory n_gsm updates from Daniel
Starke and lots of tiny driver updates and minor fixes and tweaks for
other smaller serial drivers.

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

Before the drivers rs485_config() function is called the serial core
already ensures that only one of both options RTS on send or RTS after send
is set. So remove the concerning sanity check in the driver function to
avoid redundancy.

serial: 8250_dwlib: Support for 9th bit multipoint addressing

Add 9th bit multipoint addressing mode for DW UART. 9th bit addressing
can be used only when HW RS485 is available.

Updating RAR (receive address register) is bit tricky because busy
indication is not be available when DW UART is strictly 16550
compatible, which is the case with the hardware I was testing with. RAR
should not be updated while receive is in progress which is now
achieved by deasserting RE and waiting for one frame (in case rx would
be in progress, the driver seems to have no way of knowing it w/o busy
indication). Because of this complexity, it's better to avoid doing it
unless really needed.

Lots of tiny cleanups in here, the major stuff is:

goes a long way to making things simpler for all of the different
arches

- tty documentation cleanups and movements to their own place in the
documentation tree

- old tty driver cleanups and fixes from Jiri to bring some existing
drivers into the modern world

- RS485 cleanups and unifications to make it easier for individual
drivers to support this mode instead of having to duplicate logic
in each driver

- Lots of 8250 driver updates and additions

- n_gsm continued fixes and cleanups

serial: 8250_dwlib: RS485 HW half & full duplex support

The Synopsys DesignWare UART can be configured to have HW support for
the RS485 protocol from IP version 4.0 onward. Add support for
hardware-controlled half duplex and full duplex modes.

HW will take care of managing DE and RE, the driver just gives it
permission to use either by setting both to 1.

To ask for full duplex mode, userspace sets SER_RS485_RX_DURING_TX flag
and HW will take care of the rest.

Set delay_rts_before_send and delay_rts_after_send to zero for now. The
granularity of that ABI is too coarse to be useful.
