In the current implementation, the meson-a1 configuration incorporates a
unique compatibility tag "amlogic,meson-a1-uart' within the meson-uart
driver due to its usage of the new console device name "ttyS".
Consequently, the previous compatibility tag designated for the
'amlogic,meson-gx-uart' configuration has become obsolete and is no
longer relevant to the current setup.

It is worth noting that the devname ttyS is a widely recognized tty name
and is commonly used by many uart device drivers. Given the established
usage and compatibility concerns, it may not be feasible to change the
devname for older SoCs. However, for new definitions, it is acceptable
and even recommended to use a new devname to help ensure clarity and
avoid any potential conflicts on lower or upper software levels.

Actually, the meson_uart module is already a platform_driver, but it is
currently registered manually and the uart core registration is run
outside the probe() scope, which results in some restrictions. For
instance, it is not possible to communicate with the OF subsystem
because it requires an initialized device object.
To address this issue, apply module_platform_driver() instead of direct
module init/exit routines. Additionally, move uart_register_driver() to
the driver probe(), and destroy manual console registration because it's
already run in the uart_register_driver() flow.

The UART ports created by this driver were not usable out of
the box, so let the configuration be handled by the 8250 UART
subsystem. This makes the implementation simpler and the UART
port more usable.
The 8250 UART subsystem will take care of requesting the memory
resources, but the driver needs to first read the register where
the num ports is set, so a request of the resource is needed
before registering the UART port.

This patch fixes the way the UART ports is calculated by reading

this so we can keep track of the UART line and its offset which
also improves the remove callback.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The passed parameter to sysrq handlers is a key (a character). So change
the type from 'int' to 'u8'. Let it specifically be 'u8' for two
reasons:
* unsigned: unsigned values come from the upper layers (devices) and the
tty layer assumes unsigned on most places, and
* 8-bit: as that what's supposed to be one day in all the layers built
on the top of tty. (Currently, we use mostly 'unsigned char' and
somewhere still only 'char'. (But that also translates to the former
thanks to -funsigned-char.))

Merge tag 'kbuild-fixes-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull Kbuild fixes from Masahiro Yamada:
- Fix stale help text in gconfig
- Support *.S files in compile_commands.json
- Flatten KBUILD_CFLAGS
- Fix external module builds with Rust so that temporary files are
created in the modules directories instead of the kernel tree
* tag 'kbuild-fixes-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild:
kbuild: rust: avoid creating temporary files
kbuild: flatten KBUILD_CFLAGS
gen_compile_commands: add assembly files to compilation database
kconfig: gconfig: correct program name in help text
kconfig: gconfig: drop the Show Debug Info help text
`rustc` outputs by default the temporary files (i.e. the ones saved
by `-Csave-temps`, such as `*.rcgu*` files) in the current working
directory when `-o` and `--out-dir` are not given (even if
`--emit=x=path` is given, i.e. it does not use those for temporaries).
Since out-of-tree modules are compiled from the `linux` tree,
`rustc` then tries to create them there, which may not be accessible.
Thus pass `--out-dir` explicitly, even if it is just for the temporary
files.
Similarly, do so for Rust host programs too.

Merge tag '6.5-rc2-smb3-client-fixes-ver2' of git://git.samba.org/sfrench/cifs-2.6
Pull smb client fix from Steve French:
"Add minor debugging improvement.
The change improves ability to read a network trace to debug problems
on encrypted connections which are very common (e.g. using wireshark
or tcpdump).
That works today with tools like 'smbinfo keys /mnt/file' but requires
passing in a filename on the mount (see e.g. [1]), but it often makes
more sense to just pass in the mount point path (ie a directory not a
filename).
So this fix was needed to debug some types of problems (an obvious
example is on an encrypted connection failing operations on an empty
share or with no files in the root of the directory) - so you can
simply pass in the 'smbinfo keys <mntpoint>' and get the information
that wireshark needs"

Commit 6018b585e8c6 ("tracing/histograms: Add histograms to hist_vars if
they have referenced variables") added a check to fail histogram creation
if save_hist_vars() failed to add histogram to hist_vars list. But the
commit failed to set ret to failed return code before jumping to
unregister histogram, fix it.
