Add support for SPI controllers with multiple physical SPI data lanes.
(A data lane in this context means lines connected to a serializer, so a
controller with two data lanes would have two serializers in a single
controller).
This is common in the type of controller that can be used with parallel
flash memories, but can be used for general purpose SPI as well.
To indicate support, a controller just needs to set ctlr->num_data_lanes
to something greater than 1. Peripherals indicate which lane they are
connected to via device tree (ACPI support can be added if needed).
The spi-{tx,rx}-bus-width DT properties can now be arrays. The length of
the array indicates the number of data lanes, and each element indicates
the bus width of that lane. For now, we restrict all lanes to have the
same bus width to keep things simple. Support for an optional controller
lane mapping property is also implemented.

Change spi-rx-bus-width and spi-tx-bus-width properties from single
uint32 values to arrays of uint32 values. This allows describing SPI
peripherals connected to controllers that have multiple data lanes for
receiving or transmitting two or more words in parallel.
Each index in the array corresponds to a physical data lane (one or more
wires depending on the bus width). Additional mapping properties will be
needed in cases where a lane on the controller or peripheral is skipped.
Bindings that make use of this property are updated in the same commit
to avoid validation errors.
The adi,ad4030 binding can now better describe the chips multi-lane
capabilities, so that binding is refined and gets a new example.
Converting from single uint32 to array of uint32 does not break .dts/

Use the dev_*_ratelimit() macros if the cs_dsp KUnit tests are enabled
in the build, and allow the KUnit tests to disable message output.
Some of the KUnit tests cause a very large number of log messages from
cs_dsp, because the tests perform many different test cases. This could
cause some lines to be dropped from the kernel log. Dropped lines can
prevent the KUnit wrappers from parsing the ktap output in the dmesg log.
The KUnit builds of cs_dsp export three bools that the KUnit tests can
use to entirely disable log output of err, warn and info messages. Some
tests have been updated to use this, replacing the previous fudge of a
usleep() in the exit handler of each test. We don't necessarily want to
disable all log messages if they aren't expected to be excessive,
so the rate-limiting allows leaving some logging enabled.
The rate-limited macros are not used in normal builds because it is not
appropriate to rate-limit every message. That could cause important
messages to be dropped, and there wouldn't be such a high rate of
messages in normal operation.

Add DMI entry for Huawei Matebook D (BOD-WXX9) with HEADPHONE_GPIO

This device has ES8336 codec with:
- GPIO 16 (headphone-enable) for headphone amplifier control
- GPIO 17 (speakers-enable) for speaker amplifier control
- GPIO 269 for jack detection IRQ
- 2-channel DMIC
Hardware investigation shows that both GPIO 16 and 17 are required
for proper audio routing, as headphones and speakers share the same
physical output (HPOL/HPOR) and are separated only via amplifier
enable signals.
RFC: Seeking advice on GPIO control issue:
GPIO values change in driver (gpiod_get_value() shows logical value
changes) but not physically (debugfs gpio shows no change). The same
gpiod_set_value_cansleep() calls work correctly in probe context with
msleep(), but fail when called from DAPM event callbacks.
Context information from diagnostics:
- in_atomic=0, in_interrupt=0, irqs_disabled=0
- Process context: pipewire
- GPIO 17 (speakers): changes in driver, no physical change
- GPIO 16 (headphone): changes in driver, no physical change
In Windows, audio switching works without visible GPIO changes,
suggesting possible ACPI/firmware involvement.
Any suggestions on how to properly control these GPIOs from DAPM
events would be appreciated.

Pixel normalizer is enabled with normalization factor as 1.0 for
FP16 formats in order to support FBC for those formats in xe3p_lpd.
Previously pixel normalizer gets disabled during the plane disable
routine. But there could be plane format settings without explicitly
calling the plane disable in-between and we could endup keeping the
pixel normalizer enabled for formats which we don't require that.
This is causing crc mismatches in yuv formats and FIFO underruns in
planar formats like NV12. Fix this by updating the pixel normalizer
configuration based on the pixel formats explicitly during the plane
settings arm calls itself - enable it for FP16 and disable it for
other formats in HDR capable planes.

The code local is_leap() helper was tried to be replaced by the RTC

as the kunit variant uses a signed value for the year and the RTC an
unsigned one.
Since the KUnit tests cover a 16000 year range around the epoch they use
year values that are very comfortably negative and hence get mishandled
when passed into is_leap_year().
The change was reverted, so add a comment which prevents further attempts

The vgic-debug interface implementation uses XArray marks
(`LPI_XA_MARK_DEBUG_ITER`) to "snapshot" LPIs at the start of iteration.
This modifies global state for a read-only operation and complicates
reference counting, leading to leaks if iteration is aborted or fails.
Reimplement the iterator to use dynamic iteration logic:
- Remove `lpi_idx` from `struct vgic_state_iter`.
- Replace the XArray marking mechanism with dynamic iteration using
`xa_find_after(..., XA_PRESENT)`.
- Wrap XArray traversals in `rcu_read_lock()`/`rcu_read_unlock()` to
ensure safety against concurrent modifications (e.g., LPI unmapping).
- Handle potential races where an LPI is removed during iteration by
gracefully skipping it in `show()`, rather than warning.
- Remove the unused `LPI_XA_MARK_DEBUG_ITER` definition.
This simplifies the lifecycle management of the iterator and prevents
resource leaks associated with the marking mechanism, and paves the way
for using a standard seq_file iterator.

The IDR interface is deprecated and the XArray API is the recommended
replacement. Replace the per-file IDR used to track perfmons with an
XArray. This allows us to remove the external mutex that protects the
IDR.
While here, introduce the v3d_perfmon_delete() helper to consolidate
the perfmon cleanup logic used by both v3d_perfmon_close_file() and
v3d_perfmon_destroy_ioctl().

Apply WA_16028005424 to following IPs:
Xe2_LPM, Xe2_HPM, Xe3_LPM, Xe3p_LPM
While doing this move the same WA defined for Xe3_LPG under the comment
for Xe3_LPG. It was wrongly placed under Xe3_LPM.

Pixel normalizer is enabled with normalization factor as 1.0 for
FP16 formats in order to support FBC for those formats in xe3p_lpd.
Previously pixel normalizer gets disabled during the plane disable
routine. But there could be plane format settings without explicitly
calling the plane disable in-between and we could endup keeping the
pixel normalizer enabled for formats which we don't require that.
This is causing crc mismatches in yuv formats and FIFO underruns in
planar formats like NV12. Fix this by updating the pixel normalizer
configuration based on the pixel formats explicitly during the plane
settings arm calls itself - enable it for FP16 and disable it for
other formats in HDR capable planes.
v2: avoid redundant pixel normalization setting updates
v3: moved the normalization factor definition to intel_fbc.c and some
updates to comments
v4: simplified the pixel normalizer setting handling

Introduce support in AP mode for parsing of the Operating Mode Notification
frame sent by the client to enable/disable MLO eMLSR or eMLMR if supported
by both the AP and the client.
Add drv_set_eml_op_mode mac80211 callback in order to configure underlay
driver with eMLSR/eMLMR info.
