Merge tag 'timers-v7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/daniel.lezcano/linux into timers/clocksource

- Use designated initializers for sh_mtu2, sh_cmt, and sh_tmu, and
drop the unused initializer in the platform_device_id table for
sh_mtu2 (Uwe Kleine-König)

- Remove redundant dev_err()/dev_err_probe() messages when
devm_request_*_irq() fails, as the helper already logs an error
message (Pan Chuang)

- Fix a boot hang on Allwinner D1 when a forced minimum delta is used
with the sun4i timer (Felix Yan)

- Fix an IRQ leak in the cpuhp_setup_state() error path by freeing the
IRQ on failure in the NXP PIT driver (WenTao Liang)

- Fix incorrect unmapping of shared MMIO between the clocksource and
clockevent drivers. If one of them fails to initialize, the error
path unmaps the shared MMIO region, leaving the other driver with an
invalid mapping on clps711x (Guangshuo Li)

- Make the samsung_pwm driver compatible with PREEMPT_RT by replacing
regular spinlocks with raw_spinlock_t in atomic contexts (Marek
Szyprowski)

- Use __raw_readl() and __raw_writel() instead of ioread32() and
iowrite32() to support SWAP_IO_SPACE in the rtl-otto driver (Rustam
Adilov)

- Fix a missing clk_disable_unprepare() call in the timer
initialization error path of the Armada driver (Yuho Choi)

"Here is the big set of TTY and Serial driver updates for 7.2-rc1.

Overall we end up removing more code than added, due to an obsolete
synclink_gt driver being removed from the tree, always a nice thing to
see happen.

Other than that driver removal, major things included in here are:

- max310x serial driver updates and fixes

- 8250 driver updates and rework in places to make it more "modern"

- dts file updates

- serial driver core tweaks and updates

- vt code cleanups

- vc_screen crash fixes

- other minor driver updates and cleanups

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

tty: synclink_gt: remove broken driver

The synclink_gt driver was marked as broken in commit 426263d5fb40
("tty: synclink_gt: mark as BROKEN") in July 2023 because it had severe
structural problems and there had been no evidence of users since 2016.
Since then, no meaningful improvements have been made to the driver,
and it is unlikely that will ever happen due to the lack of interest.
Drop the driver and references to it in comments and documentation.
include/uapi/linux/synclink.h is also removed. The only use of this
header I have found is the linux-raw-sys Rust crate. It generates
bindings for all UAPI headers, but has a hardcoded list of headers and
ioctls, including this one, so that does not indicate that anyone is
using it. I have sent a pull request to remove the include and ioctl
definitions for this header (see the link below).

- New option "printk.debug_non_panic_cpus" allows to store printk
messages from non-panic CPUs during panic. It might be useful when
panic() fails. It is disabled by default because it increases the
chance to see the messages printed before panic() and on the
panic-CPU.

- New build option "CONFIG_NULL_TTY_DEFAULT_CONSOLE" allows to build
kernel without the virtual terminal support which prefers ttynull
over serial console.

- Do not unblank suspended consoles.

printk: Add an option to allow ttynull to be a default console device

The new option is CONFIG_NULL_TTY_DEFAULT_CONSOLE.

if enabled, and CONFIG_VT is disabled, ttynull will become the default
primary console device.

ttynull will be the only console device usually with this option enabled.
Some architectures do call add_preferred_console() which may add another
console though.

Motivation:

Many distributions ship with CONFIG_VT enabled. On tested desktop hardware
if CONFIG_VT is disabled, the default console device falls back to
/dev/ttyS0 instead of /dev/tty.

This could cause issues in user space, and hardware problems:

1. The user space issues include the case where /dev/ttyS0 is
disconnected, and the TCGETS ioctl, which some user space libraries use
as a probe to determine if a file is a tty, is called on /dev/console and
fails. Programs that call isatty() on /dev/console and get an incorrect
false value may skip expected logging to /dev/console.

2. The hardware issues include the case if a user has a science instrument
or other device connected to the /dev/ttyS0 port, and they were to upgrade
to a kernel that is disabling the CONFIG_VT option, kernel logs will then
be sent to the device connected to /dev/ttyS0 unless they edit their
kernel command line manually.

The new CONFIG_NULL_TTY_DEFAULT_CONSOLE option will give users and
distribution maintainers an option to avoid this. Disabling CONFIG_VT and
enabling CONFIG_NULL_TTY_DEFAULT_CONSOLE will ensure the default kernel
console behavior is not dependent on hardware configuration by default, and
avoid unexpected new behavior on devices connected to the /dev/ttyS0 serial
port.
