sp_device->dev_vdata points to only const data (see 'static const struct
sp_dev_vdata dev_vdata'), so can be made pointer to const for code
safety.
Update also sp_get_acpi_version() function which returns this pointer to
'pointer to const' for code readability, even though it is not needed.
On the other hand, do not touch similar function sp_get_of_version()
because it will be immediately removed in next patches.

Driver's probe function matches against driver's of_device_id table, so
of_match_node() can be simplified with of_device_get_match_data().
This requires changing the enum used in the driver match data entries to
non-zero, to be able to recognize error case of
of_device_get_match_data().

Convention is to place MODULE_DEVICE_TABLE() immediately after
definition of the affected table, so one can easily spot missing such.
There is on the other hand no benefits of putting MODULE_DEVICE_TABLE()
far away.

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 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566af ("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.

Currently, SSPPs are assigned to a maximum of two pipes. However,
quad-pipe usage scenarios require four pipes and involve configuring
two stages. In quad-pipe case, the first two pipes share a set of
mixer configurations and enable multi-rect mode when certain
conditions are met. The same applies to the subsequent two pipes.
Assign SSPPs to the pipes in each stage using a unified method and
to loop the stages accordingly.

Some devices (such as Smaug) report having MOTION_SENSE_FIFO but do not
support controlling the behaviour of the FIFO interrupt via the
FIFO_INT_ENABLE command and in these cases the interrupt is always
enabled. However, currently the code assumes that if MOTION_SENSE_FIFO
is supported then so is FIFO_INT_ENABLE, and when it tries to enable
the interrupt via this command and an unsupported device reports a
failure it then propagates this into failing the sensors probe.
Interpret the return value -EINVAL as a device where FIFO_INT_ENABLE is
not present and the interrupt is always enabled.

Compute more of the required FB layout information to boot the GSP
firmware.
This information is dependent on the firmware itself, so first we need
to import and abstract the required firmware bindings in the `nvfw`
module.
Then, a new FB HAL method is introduced in `fb::hal` that uses these
bindings and hardware information to compute the correct layout
information.
This information is then used in `fb` and the result made visible in
`FbLayout`.
These 3 things are grouped into the same patch to avoid lots of unused
warnings that would be tedious to work around. As they happen in
different files, they should not be too difficult to track separately.

Add support for the PHY LED controller in the MSCC VSC85xx driver. The
implementation provides LED brightness and hardware control through the
LED subsystem and integrates with the standard 'netdev' trigger.
Introduce new register definitions for the LED behavior register
(MSCC_PHY_LED_BEHAVIOR = 30) and the LED combine disable bits, which
control whether LEDs indicate link-only or combined link and activity
status. Implement a helper, vsc8541_led_combine_disable_set(), to update
these bits safely using phy_modify().
Add support for LED brightness control and hardware mode configuration.
The new callbacks implement the standard LED class operations, allowing
user control through sysfs. The brightness control maps to PHY LED force
on/off modes. The hardware control get and set functions translate
between the PHY-specific LED mode encodings and the LED subsystem
TRIGGER_NETDEV_* rules.
The combine feature is managed automatically based on the selected
rules. When both RX and TX activity are disabled, the combine feature is
turned off, causing LEDs to indicate link-only status. When either RX or
TX activity is enabled, the combine feature remains active and LEDs
indicate combined link and activity.
Register the LED callbacks for all VSC85xx PHY variants so that the LED
subsystem can manage their indicators consistently. Existing device tree
LED configuration and default behavior are preserved.

Unify the probe implementations of the VSC85xx PHY family into a single
vsc85xx_probe_common() helper. The existing probe functions for the
vsc85xx, vsc8514, vsc8574, and vsc8584 variants contained almost
identical initialization logic, differing only in configuration
parameters such as the number of LEDs, supported LED modes, hardware
statistics, and PTP support.
Introduce a vsc85xx_probe_config structure to describe the per-variant
parameters, and move all common setup code into the shared helper. Each
variant's probe function now defines a constant configuration instance
and calls vsc85xx_probe_common().
Also mark the default LED mode array parameter as const to match its
usage.

Documentation build reported:
Warning: drivers/dpll/zl3073x/fw.c:365 function parameter 'comp' not described in 'zl3073x_fw_component_flash'
Warning: drivers/dpll/zl3073x/fw.c:365 expecting prototype for zl3073x_flash_bundle_flash(). Prototype was for zl3073x_fw_component_flash() instead
Warning: drivers/dpll/zl3073x/fw.c:365 No description found for return value of 'zl3073x_fw_component_flash'
The kernel-doc comment above `zl3073x_fw_component_flash()` used
the wrong function name (`zl3073x_flash_bundle_flash`) and omitted
the `@comp` parameter. Update the comment to correctly document
the `zl3073x_fw_component_flash()` function and its arguments.

The function mlxsw_sp_flower_stats() calls mlxsw_sp_acl_ruleset_get() to
obtain a ruleset reference. If the subsequent call to
mlxsw_sp_acl_rule_lookup() fails to find a rule, the function returns
an error without releasing the ruleset reference, causing a memory leak.
Fix this by using a goto to the existing error handling label, which
calls mlxsw_sp_acl_ruleset_put() to properly release the reference.

All of the objects in drivers/virt/ have their own configuration symbols to
gate compilation. I.e. nothing gets added to the kernel with
CONFIG_VIRT_DRIVERS=y in isolation.
Unconditionally descend into drivers/virt/ so that consumers do not need to
add an additional CONFIG_VIRT_DRIVERS dependency.
Fix warnings of the form:
Kconfig warnings: (for reference only)
WARNING: unmet direct dependencies detected for TSM
Depends on [n]: VIRT_DRIVERS [=n]
Selected by [y]:
- PCI_TSM [=y] && PCI [=y]
...where PCI_TSM selects CONFIG_TSM, but fails to select
CONFIG_VIRT_DRIVERS.

Calls to xe_force_wake_put() should generally pass the exact reference
returned by xe_force_wake_get(). Since OA grabs and releases forcewake
in different functions, xe_oa_stream_destroy() is currently calling put
with a hardcoded ALL mask. Although this works for now, it's somewhat
fragile in case OA moves to more precise power domain management in the
future.
Stash the original reference obtained during stream initialization
inside the stream structure so that we can use it directly when the
stream is destroyed.
