- 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)

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)

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

PM: sleep: Allow disabling DPM watchdog by default

Introduce the "dpm_watchdog_enabled" module parameter to allow the DPM
watchdog to be enabled or disabled at boot time and runtime.

Additionally,

PM: sleep: Allow disabling DPM watchdog by default

Introduce the "dpm_watchdog_enabled" module parameter to allow the DPM
watchdog to be enabled or disabled at boot time and runtime.

Additionally, introduce the CONFIG_DPM_WATCHDOG_ENABLED Kconfig option
to set the default value of the module parameter at compile time.

The primary motivation for this configurability resolves around Android
GKI (Generic Kernel Image). We want to enable CONFIG_DPM_WATCHDOG in
the GKI so the feature is available. However, because the GKI is shared
across many different devices, we don't want to inadvertently affect
devices that are unaware of this feature. This provides a way to
compile it in, but keep it disabled by default for those devices via the
kernel command line or module parameters.

To maintain backward compatibility, CONFIG_DPM_WATCHDOG_ENABLED relies
on `default y`. Previously, the DPM watchdog was always active if
CONFIG_DPM_WATCHDOG was set. Defaulting this new option to 'y' ensures
that the behavior remains unchanged for existing users and defconfigs
when they upgrade.

"Over a half of the changes here are cpufreq updates that include core
modifications, fixes of the old-style governors, new hardware support
in drivers, assorded driver fixes and cleanups, and the removal of one

exposing redundant C-states if PC6 is disabled and there are new
sysctl knobs for device suspend/resume watchdog timeouts, hibernation

Merge tag 'pm-6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"There are quite a few interesting things here, including new hardware
support, new features, some bug fixes and documentation updates. In
addition, there are a usual bunch of minor fixes and cleanups all
over.

In the new hardware support category, there are intel_pstate and
intel_rapl driver updates to support new processors, Panther Lake,
Wildcat Lake, Noval Lake, and Diamond Rapids in the OOB mode, OPP and
bandwidth allocation support in the tegra186 cpufreq driver, and
JH7110S SOC support in dt-platdev cpufreq.

The new features are the PM QoS CPU latency limit for suspend-to-idle,
the netlink support for the energy model management, support for
terminating system suspend via a wakeup event during the sync of file
systems, configurable number of hibernation compression threads, the
runtime PM auto-cleanup macros, and the "poweroff" PM event that is
expected to be used during system shutdown.

Bugs are mostly fixed in cpuidle governors, but there are also fixes
elsewhere, like in the amd-pstate cpufreq driver.

Documentation updates include, but are not limited to, a new doc on
debugging shutdown hangs, cross-referencing fixes and cleanups in the
intel_pstate documentation, and updates of comments in the core
hibernation code.

- Fix a reverse condition in the teo cpuidle governor and drop a
misguided target residency check from it (Rafael Wysocki)

PM: QoS: Introduce a CPU system wakeup QoS limit

Some platforms supports multiple low power states for CPUs that can be used
when entering system-wide suspend. Currently we are always selecting the
deepest possible state for the CPUs, which can break the system wakeup
latency constraint that may be required for a use case.

Let's take the first step towards addressing this problem, by introducing
an interface for user space, that allows us to specify the CPU system
wakeup QoS limit. Subsequent changes will start taking into account the new
QoS limit.
