clamp() expects compatible operand types. The period calculation uses
nanosecond constants, while the local target variable was narrower than
the upper bound expression.
Make target unsigned long and use unsigned long bounds, including
NSEC_PER_USEC for the upper limit. This keeps the operands naturally
aligned without adding casts.

Add support for the AD4880, a dual-channel 20-bit 40MSPS SAR ADC with
integrated fully differential amplifiers (FDA).
The AD4880 has two independent ADC channels, each with its own SPI
configuration interface. The driver uses spi_new_ancillary_device() to
create an additional SPI device for the second channel, allowing both
channels to share the same SPI bus with different chip selects.

Add a new function to get an IIO backend by its index in the
io-backends device tree property. This is useful for multi-channel
devices that have multiple backends, where looking up by index is
more straightforward than using named backends.
Extract __devm_iio_backend_fwnode_get_by_index() from the existing
__devm_iio_backend_fwnode_get(), taking the index directly as a
parameter. The new public API devm_iio_backend_get_by_index() uses
the index to find the backend reference in the io-backends property,
avoiding the need for io-backend-names.

Add PIX path support to the CSID-340 driver. The hardware exposes a
dedicated PIX interface in addition to the existing RDI paths, but
the driver only supported RDI stream configuration so far.
The PIX path is configured similarly to RDI but requires decode-format
to be specified.
The PIX pipeline can subsequently perform further processing,
including scaling, cropping, and statistics.

The CSID-340 block uses different register offsets for the PIX and RDI
interfaces, but the driver previously indexed these registers directly
with the camss port number. This happened to work for RDI because the
port index matches the RDI register layout, but this assumption breaks
with upcoming PIX interface support
Introduce an explicit port-to-interface mapping and use the mapped iface
index when programming CSID_CFG0 and CSID_CTRL. This replaces the
standalone __csid_ctrl_rdi() helper and simplifies the RDI stream setup
path.
Also correct the CSID_CFG0/CTRL base offsets and clean up the code in
preparation for full PIX path support.
Like RDI, PIX outputs Bayer frames but can also achieve some image
processing such as scaling, cropping and generating statitics (e.g.
histogram), it also offer more flexebility in term of image alignment
and stride. All of that can then later be leveraged to improve
software or hardware frames post-processing.

The former RDI-specific register definitions (CSID_RDI_CFG0/CTRL) are
renamed to unified CSID_CFG0/CSID_CTRL variants, as their layout is
interface agnostic. This refactoring provides the foundation for

On multi-socket platforms each socket has its own BPMP that is
registered with the kernel, so the existing single fixed "bpmp"
debugfs directory name cannot accommodate more than one instance.
Group the per-socket BPMP debugfs entries under a shared top-level
/sys/kernel/debug/bpmp/ directory, with each socket's BPMP device
under a "<numa-node-id>-bpmp" subdirectory:
/sys/kernel/debug/bpmp/0-bpmp/...
/sys/kernel/debug/bpmp/1-bpmp/...
For a multi-socket platform, the root debugfs bpmp/ directory is created
by the first BPMP device that is populated. For single-socket platforms,
the existing directory structure is preserved.

The Tegra PMC power-off handler exists solely to reboot the Nexus 7 into
a special bootloader mode when a USB cable is connected, so that the
bootloader can display battery status instead of powering off. There is
no reason to register it on any other Tegra board.
Guard the registration behind of_machine_is_compatible("asus,grouper")
and rename the handler to tegra_pmc_grouper_power_off_handler to make
its scope explicit. The of_machine_is_compatible() check inside the
handler itself is now redundant and is removed.
This also avoids occupying SYS_OFF_PRIO_FIRMWARE on boards that have
other handlers at that priority level.

For legacy purposes, an early PMC context is needed to support certain
drivers and functionalities. However, when the PMC driver is probed in
the later boot stages, the early context is no longer needed. Allocate
the PMC context dynamically at probe time so that it can be used going
forward.
While at it, rename the early PMC context to more accurately reflect
what it is used for. It's technically not only for early boot stages,
but also to support some code that doesn't have a way of obtaining the
correct context otherwise (e.g. no access to device tree).

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.
The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.
This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64

Clients can be registered from bus notifier callbacks so the debugfs
directory needs to be created before registering the adapter as clients
use that directory as their debugfs parent.
Move debugfs creation before adapter registration to avoid having
clients create their debugfs directories in the debugfs root (which is
also more likely to fail due to name collisions).
Note that failure to allocate the adapter name must now be handled
explicitly as debugfs_create_dir() cannot handle a NULL name (unlike
device_add() which returns an error).

Commit eac69475b01f ("media: rc: igorplugusb: heed coherency
rules") changed the control request storage from an embedded struct to
an allocated pointer so it can obey DMA coherency rules.
However, the driver still passes &ir->request to usb_fill_control_urb().
That points the URB setup packet at the pointer field itself rather than
at the allocated struct usb_ctrlrequest.
USB core then interprets pointer bytes as the setup packet. This can
produce an invalid bRequestType and trigger the control direction warning
reported by syzbot:
usb 2-1: BOGUS control dir, pipe 80003580 doesn't match bRequestType 0
Pass ir->request itself as the setup packet.

virtio_i2c_probe() synchronously probes child i2c drivers on the bus,
but peripherals may use the bus at probe for tasks like reading a chip
id. The vhost-user-i2c backend stalls at such probes unless DRIVER_OK
is already set before the virtqueue is first kicked.
Set DRIVER_OK explicitly before i2c_add_adapter(), as done for the
same reason in commit f5866db64f34 ("virtio_console: enable VQs
early") and commit 71e4b8bf0482 ("virtio_rpmsg: set DRIVER_OK before
using device").

The HFI sys ops were previously initialized in probe() but, we don't
have firmware loaded at probe time. Since HFI is tightly coupled to
firmware, initialize the HFI sys ops after firmware has been successfully
loaded and booted.

from the struct is not actually used. Drop the struct completely and use

On X1P42100 the Iris block has an extra BSE clock. Wire this clock into
the power on/off sequence.
The BSE clock is used to drive the Bin Stream Engine, which is a sub-block
of the video codec hardware responsible for bitstream-level processing. It
is required to be enabled separately from the core clock to ensure proper
codec operation.

The existing iris_vpu_dec_comv_size() used VIDEO_MAX_FRAME (32) as
num_comv count unconditionally when calculating the co-located motion
vector (COMV) buffer size. This resulted in an oversized COMV buffer
allocation throughout decode session, wasting memory regardless of
actual number of buffers required.
For VPU3x and VPU4x platforms, introduce iris_vpu3x_4x_dec_comv_size() to
replace iris_vpu_dec_comv_size(). These derive num_comv dynamically, it
uses inst->fw_min_count once the firmware has reported its buffer
requirements, and fallback to output count during initialization before
firmware has communicated its requirements. This aligns the COMV buffer
size to the actual count needed rather than always allocating with fixed
VIDEO_MAX_FRAME value.
Additionally, during iris_vdec_inst_init(), fw_min_count was initialized
to MIN_BUFFERS instead of 0. This masked the fallback logic and caused the
COMV size calculation to use MIN_BUFFERS even before firmware had reported
its actual requirements. Fix this by initializing fw_min_count to 0.
During testing of 1080p AVC, it reduces the COMV buffer size from 32.89MB
to 6.16MB per decode session, significantly reducing memory consumption.

The driver was using a fixed default FPS value when calculating the VPU
frequency. This caused wrong frequency requests for high‑frame‑rate
streams, for example 4K at 240 FPS. Because of this, the hardware was
running at a lower frequency than needed.
Add the FPS measurement based on the decoder input buffer arrival rate.
The measured FPS is stored per instance and used in frequency calculation
instead of the fixed default FPS. The value is clamped so that it does
not exceed platform limits. Add a VPP firmware overhead when running in
STAGE_2.
