Current code only supports usage cases with one pair of mixers at
most. To support quad-pipe usage case, two pairs of mixers need to
be reserved. The lm_count for all pairs is cleared if a peer
allocation fails in current implementation. Reset the current lm_count
to an even number instead of completely clearing it. This prevents all
pairs from being cleared in cases where multiple LM pairs are needed.

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.

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.

fragile in case OA moves to more precise power domain management in the
future.

Extract the OEN register write with PWPR protection logic into a helper
function to eliminate code duplication between rzg2l_write_oen() and
rzg2l_pinctrl_resume_noirq().
Introduce rzg2l_oen_write_with_pwpr() helper that encapsulates the
PWPR unlock, OEN register write, and PWPR lock sequence. This helper
must be called with pctrl->lock already held by the caller.

The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs have four SPI
peripherals, each with their own clock divider, which divides PLL4 by
either 24, 25, 30 or 32, similar to the SCI peripheral.
The dividers feed into the usual module clocks.
Add them all.

IEEE 1394 defines the split, concatenated, and unified transaction.
To support the split transaction, core function uses linked list to
maintain the transactions waiting for acknowledge packet. After clearing
sources of hardware interrupts, the acknowledge packet is no longer
handled, therefore it is required to abort the pending transactions.
This commit executes callback with RCODE_CANCELLED for the pending
transactions at card removal.

Add support for Partial-IO poweroff. In Partial-IO pins of a few
hardware units can generate system wakeups while DDR memory is not
powered resulting in a fresh boot of the system. These hardware units in
the SoC are always powered so that some logic can detect pin activity.
If the system supports Partial-IO as described in the fw capabilities, a
sys_off handler is added. This sys_off handler decides if the poweroff
is executed by entering normal poweroff or Partial-IO instead. The
decision is made by checking if wakeup is enabled on all devices that
may wake up the SoC from Partial-IO.
The possible wakeup devices are found by checking which devices
reference a "Partial-IO" system state in the list of wakeup-source
system states. Only devices that are actually enabled by the user will
be considered as an active wakeup source. If none of the wakeup sources
is enabled the system will do a normal poweroff. If at least one wakeup
source is enabled it will instead send a TI_SCI_MSG_PREPARE_SLEEP
message from the sys_off handler. Sending this message will result in an
immediate shutdown of the system. No execution is expected after this
point. The code will wait for 5s and do an emergency_restart afterwards
if Partial-IO wasn't entered at that point.
A short documentation about Partial-IO can be found in section 6.2.4.5
of the TRM at

Check the header flags if an response is expected or not. If it is not
expected skip the receive part of ti_sci_do_xfer(). This prepares the
driver for one-way messages as prepare_sleep for Partial-IO.

Fix runtime PM usage count underflow caused by calling
pm_runtime_put_autosuspend() twice with only one corresponding
pm_runtime_get_noresume() call. This triggers the warning:
"Runtime PM usage count underflow!"

counting.

The "probe_setup_failed" label calls pm_runtime_disable(), but
pm_runtime_enable() was placed after a possible jump to this label.
When cqspi_setup_flash() fails, control jumps to the label without
pm_runtime_enable() being called, leading to unbalanced PM runtime
reference counting.
Move pm_runtime_enable() and associated calls above the first
possible branch to "probe_setup_failed" to ensure balanced
enable/disable calls across all error paths.
