ice_deinit_dev() takes care of turning off adminq processing, which is
much needed during driver teardown (remove, reset, error path). Move it
to the very end where applicable.
For example, ice_deinit_hw() called after adminq deinit slows rmmod on
my two-card setup by about 60 seconds.
ice_init_dev() and ice_deinit_dev() scopes were reduced by previous
commits of the series, with a final touch of extracting ice_init_dev_hw()
out now (there is no deinit counterpart).
Note that removed ice_service_task_stop() call from ice_remove() is placed
in the ice_deinit_dev() (and stopping twice makes no sense).

Move udp_tunnel_nic setup and ice_req_irq_msix_misc() call into
ice_init_pf(), remove some redundancy in the former while moving.
Move ice_free_irq_msix_misc() call into ice_deinit_pf(), to mimic
the above in terms of needed cleanup. Guard it via emptiness check,
to keep the allowance of half-initialized pf being cleaned up.

Add a driver for Arm Ethos-U65/U85 NPUs. The Ethos-U NPU has a
relatively simple interface with single command stream to describe
buffers, operation settings, and network operations. It supports up to 8
memory regions (though no h/w bounds on a region). The Ethos NPUs
are designed to use an SRAM for scratch memory. Region 2 is reserved
for SRAM (like the downstream driver stack and compiler). Userspace
doesn't need access to the SRAM.
The h/w has no MMU nor external IOMMU and is a DMA engine which can
read and write anywhere in memory without h/w bounds checks. The user
submitted command streams must be validated against the bounds of the
GEM BOs. This is similar to the VC4 design which validates shaders.
The job submit is based on the rocket driver for the Rockchip NPU
utilizing the GPU scheduler. It is simpler as there's only 1 core rather
than 3.
Tested on i.MX93 platform (U65) and FVP (U85) with Mesa Teflon
support.

Optimize the PLIC driver by maintaining the interrupt enable state in the
handler's enable_save array during normal operation rather than only during
suspend/resume. This eliminates the need to read enable registers during
suspend and makes the enable state immediately available for other
purposes.
Let __plic_toggle() update both the hardware registers and the cached
enable_save state atomically within the existing enable_lock protection.
That allows to remove the suspend-time enable register reading since
handler::enable_save now always reflects the current state.

Move ice_init_interrupt_scheme() prior ice_init_pf().
To enable the move ice_set_pf_caps() was moved out from ice_init_pf()
to the caller (ice_init_dev()), and placed prior to the irq scheme init.
The move makes deinit order of ice_deinit_dev() and failure-path of
ice_init_pf() match (at least in terms of not calling
ice_clear_interrupt_scheme() and ice_deinit_pf() in opposite ways).
The new order aligns with findings made by Jakub Buchocki in
the commit 24b454bc354a ("ice: Fix ice module unload").

Hardware target implements an address space larger than that PCI BAR can
map. In order to be able to access the whole target address space, the
BAR space is split into 4 segments, of which the last 3, called windows,
can be dynamically mapped to the desired area. This is achieved by
updating WINDOW_REG_ADDRESS register with appropriate window value.
Currently each time when accessing a register that beyond WINDOW_START,
host calculates the window value and caches it after window update,
this way next time when accessing a register falling in the same window,
host knows that the window is already good hence no additional update
needed.
However this mechanism breaks after global reset is triggered in
ath12k_pci_soc_global_reset(), because with global reset hardware resets
WINDOW_REG_ADDRESS register hence the window is not properly mapped any
more. Current host does nothing about this, as a result a subsequent
register access may not work as expected if it falls in a window same as
before.
Although there is no obvious issue seen now, better to fix it to avoid
future problem. The fix is done by restoring the window register after
global reset.

Add support for handling BSS color collision events reported by firmware.
There are two scenarios where a BSS color collision may be detected:
1. The AP's MAC detects the collision directly, and firmware reports a
BSS color collision event to the host.
2. A STA associated with the AP detects the collision. The notification
frame from the peer is routed directly to the AP firmware, which handles
it and sends the BSS color collision event to the host.
Add logic to parse and handle such events, and pass the data
up to mac80211.
Unlike CSA, firmware does not provide an offload mechanism for BSS color
change. Instead, the color change process is triggered via beacon offload
TX completion events sent by firmware.
BSS color feature is enabled depending on service flag advertised by
firmware, based on which color change functionality is invoked.
This change builds upon the following ath11k patch.

A different structure is stored in drvdata for the drivers which used
that duplicate function, but h4_recv_buf() assumes drvdata is always an
hci_uart structure.
Consequently, alignment and padding are now randomly corrupted for
btmtkuart, btnxpuart, and bpa10x in h4_recv_buf(), causing erratic
breakage.
Fix this by making the hci_uart structure the explicit argument to
h4_recv_buf(). Every caller already has a reference to hci_uart, and
already obtains the hci_hdev reference through it, so this actually
eliminates a redundant pointer indirection for all existing callers.

In the current btintel_pcie driver implementation, when an interrupt is
received, the driver checks for the alive cause before the TX/RX cause.
Handling the alive cause involves resetting the TX/RX queue indices.
This flow works correctly when the causes are mutually exclusive.
However, if both cause bits are set simultaneously, the alive cause
resets the queue indices, resulting in an event packet drop and a
command timeout. To fix this issue, the driver is modified to handle all
other causes before checking for the alive cause.

This patch adds logic to handle power management control when the
Bluetooth function is closed during the SDIO reset sequence.
Specifically, if BT is closed before reset, the driver enables the

These changes ensure proper power management and device state consistency
across the reset flow.

UCSI v2 specification has increased the MSG_IN and MSG_OUT size from
16 bytes to 256 bytes each for the message exchange between OPM and PPM
This makes the total buffer size increase from 48 bytes to 528 bytes.
Update the buffer size to support this increase.

There is a possibility of user needs for USB mode switching on boards
that lack external hardware support for dynamic host/device role
detection. This is particularly relevant in automotive applications
where userspace applications need to switch USB roles (host to device)
at runtime for CarPlay/Android Auto integration.
Add an `allow_userspace_control` flag to handle such cases. When
enabled, it exposes a sysfs attribute that allows userspace to switch
the USB role manually between host and device. This provides flexibility
for platforms that cannot rely on hardware-based mode detection.
The role switch can be done as below
echo host > /sys/class/usb_role/<ADDR>.usb-role-switch/role
echo device > /sys/class/usb_role/<ADDR>.usb-role-switch/role

Some devices, like the Grandstream GUV3100 webcam, have an invalid UVC
descriptor where multiple entities share the same ID, this is invalid
and makes it impossible to make a proper entity tree without heuristics.
We have recently introduced a change in the way that we handle invalid
entities that has caused a regression on broken devices.
Implement a new heuristic to handle these devices properly.

During DT-binding review for extending the V4L2 camera sensor privacy LED
support to systems using devicetree, it has come up that having a "-led"
suffix for the LED name / con_id is undesirable since it already is clear
that it is a LED.
Drop the "-led" suffix from the con_id in both the lookup table in
the int3472 code, as well as from the con_id led_get() argument in
the v4l2-subdev code.

Some firmware implementations use the "Ones" ASL opcode to produce
an integer with all bits set in order to indicate missing speed or
power readings. This however only works when using 32-bit integers,
as the ACPI spec requires a 32-bit integer (0xFFFFFFFF) to be
returned for missing speed/power readings. With 64-bit integers the
"Ones" opcode produces a 64-bit integer with all bits set, violating
the ACPI spec regarding the placeholder value for missing readings.
Work around such buggy firmware implementation by also checking for
64-bit integers with all bits set when reading _FST.
