These updates came a little late, or were based on a later 6.18-rc
tag than the others:
- A new driver for cache management on cxl devices with memory shared
in a coherent cluster. This is part of the drivers/cache/ tree, but
unlike the other drivers that back the dma-mapping interfaces, this
one is needed only during CPU hotplug.
- A shared branch for reset controllers using swnode infrastructure
- Added support for new SoC variants in the Amlogic soc_device
identification
- Minor updates in Freescale, Microchip, Samsung, and Apple SoC drivers

Two fixes for Exynos PMU (Power Management Unit) driver:

2. Drop device refcount when requesting device regmap with
exynos_get_pmu_regmap_by_phandle(). Issue was introduced much
earlier (around v6.9), with code being rewritten in between.

Apple SoC driver updates for 6.18
Two small fixes:
- mailbox: Stop leaking a reference to the mbox platform device during
lookup
- sart: drop device reference after lookup since it's no longer used
afterwards

Make sure to drop the reference taken when looking up the PMU device and
its regmap.
Note that holding a reference to a device does not prevent its regmap
from going away so there is no point in keeping the reference.

Commit 78b72897a5 ("soc: samsung: exynos-pmu: Enable CPU Idle for
gs101") added system wide suspend/resume callbacks to Exynos PMU driver,
but some items used by these callbacks are initialized only on
GS101-compatible boards. Move that initialization to exynos_pmu_probe()
to avoid potential lockdep warnings like below observed during system
suspend/resume cycle:
INFO: trying to register non-static key.
The code is fine but needs lockdep annotation, or maybe
you didn't initialize this object before use?
turning off the locking correctness validator.

Currently if a user enqueues a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistency cannot be addressed without refactoring the API.
alloc_workqueue() treats all queues as per-CPU by default, while unbound
workqueues must opt-in via WQ_UNBOUND.
This default is suboptimal: most workloads benefit from unbound queues,
allowing the scheduler to place worker threads where they’re needed and
reducing noise when CPUs are isolated.
This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:
commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")
This change adds a new WQ_PERCPU flag to explicitly request
alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU.
Once migration is complete, WQ_UNBOUND can be removed and unbound will
become the implicit default.

Support for hardware-keymanager v1 support for wrapped keys is introduce
in the ICE driver.
Support for the new Kaanapali mobile platform is added to last-level

UBWC driver gains support for the Monaco and Glymur platforms.
The PMIC GLINK driver is extended to handle the differences found in
targets where the related firmware runs on the SoCCP.
Support for running on targets without initialized SMEM is provided, by
reworking the SMEM driver to differentiate between "not yet probed" and
"probed but there was no SMEM". An unwanted WARN_ON() that triggered if
clients asked for a SMEM item beyond the currently running system's
limit, was removed, to allow new use cases to gracefully fail on old
targets.
The Qualcomm socinfo driver is extended with support for version 20
through 23 and support for providing version information about more than
32 remote processors. Identifiers for QCS6490 and SM8850 are also added.
Additionally, a number of smaller bug fixes and cleanups in PBS, OCMEM,
GSBI, TZMEM, and MDT-loader are included.

Add a parameter to syscore operations to allow passing contextual data,
which in turn enables refactoring of drivers to make them independent of
global data. This initially only contains the API changes along with the
updates for existing drivers. Subsequent work will make use of this to
improve drivers.

syscore: Changes for v6.19-rc1
Add a parameter to syscore operations to allow passing contextual data,
which in turn enables refactoring of drivers to make them independent of
global data. This initially only contains the API changes along with the
updates for existing drivers. Subsequent work will make use of this to
improve drivers.

2. PMU driver: Allow specifying list of valid registers for the custom
regmap used on Google GS101 SoC. The PMU (Power Management Unit) on
that SoC uses more complex access to registers than simple MMIO and
invalid registers trigger aborts halting the system.
3. Few minor cleanups.
4. Several new bindings for compatible devices.

Similar to the RK3288, the RK3368 has two different implementations of
the PWM block inside the SoC - the newer ones that we have a driver for
and that is used on every SoC and a previous variant that was likely
left as a fallback if the new one creates problems.
The devicetree is already set up for the new variant, so make sure
we actually use it - similar to the RK3288.

There is currently a problem where, in the specific case of SMEM not
initialized by SBL, any SMEM API wrongly returns PROBE_DEFER
communicating wrong info to any user of this API.
A better way to handle this would be to track the SMEM state and return
a different kind of error than PROBE_DEFER.
Rework the __smem handle to always init it to the error pointer
-EPROBE_DEFER following what is already done by the SMEM API.
If we detect that the SBL didn't initialized SMEM, set the __smem handle
to the error pointer -ENODEV.
Also rework the SMEM API to handle the __smem handle to be an error
pointer and return it appropriately.
This way user of the API can react and return a proper error or use
fallback way for the failing API.
While at it, change the return error when SMEM is not initialized by SBL
also to -ENODEV to make it consistent with the __smem handle and use
dev_err_probe() helper to return the message.
