Pull kthread updates from Frederic Weisbecker:
"Kthreads affinity follow either of 4 existing different patterns:
1) Per-CPU kthreads must stay affine to a single CPU and never
execute relevant code on any other CPU. This is currently handled
by smpboot code which takes care of CPU-hotplug operations.
Affinity here is a correctness constraint.
2) Some kthreads _have_ to be affine to a specific set of CPUs and
can't run anywhere else. The affinity is set through
kthread_bind_mask() and the subsystem takes care by itself to
handle CPU-hotplug operations. Affinity here is assumed to be a
correctness constraint.
3) Per-node kthreads _prefer_ to be affine to a specific NUMA node.
This is not a correctness constraint but merely a preference in
terms of memory locality. kswapd and kcompactd both fall into this
category. The affinity is set manually like for any other task and
CPU-hotplug is supposed to be handled by the relevant subsystem so
that the task is properly reaffined whenever a given CPU from the
node comes up. Also care should be taken so that the node affinity
doesn't cross isolated (nohz_full) cpumask boundaries.
4) Similar to the previous point except kthreads have a _preferred_
affinity different than a node. Both RCU boost kthreads and RCU
exp kworkers fall into this category as they refer to "RCU nodes"
from a distinctly distributed tree.
Currently the preferred affinity patterns (3 and 4) have at least 4
identified users, with more or less success when it comes to handle
CPU-hotplug operations and CPU isolation. Each of which do it in its
own ad-hoc way.
This is an infrastructure proposal to handle this with the following
API changes:
- kthread_create_on_node() automatically affines the created kthread
to its target node unless it has been set as per-cpu or bound with
kthread_bind[_mask]() before the first wake-up.
- kthread_affine_preferred() is a new function that can be called
right after kthread_create_on_node() to specify a preferred
affinity different than the specified node.
When the preferred affinity can't be applied because the possible
targets are offline or isolated (nohz_full), the kthread is affine to
the housekeeping CPUs (which means to all online CPUs most of the time
or only the non-nohz_full CPUs when nohz_full= is set).
kswapd, kcompactd, RCU boost kthreads and RCU exp kworkers have been
converted, along with a few old drivers.
Summary of the changes:
- Consolidate a bunch of ad-hoc implementations of
kthread_run_on_cpu()
- Introduce task_cpu_fallback_mask() that defines the default last
resort affinity of a task to become nohz_full aware
- Add some correctness check to ensure kthread_bind() is always
called before the first kthread wake up.
- Default affine kthread to its preferred node.
- Convert kswapd / kcompactd and remove their halfway working ad-hoc
affinity implementation
- Implement kthreads preferred affinity
- Unify kthread worker and kthread API's style
- Convert RCU kthreads to the new API and remove the ad-hoc affinity
implementation"

kthread_create() creates a kthread without running it yet. kthread_run()
creates a kthread and runs it.
On the other hand, kthread_create_worker() creates a kthread worker and
runs it.
This difference in behaviours is confusing. Also there is no way to
create a kthread worker and affine it using kthread_bind_mask() or
kthread_affine_preferred() before starting it.
Consolidate the behaviours and introduce kthread_run_worker[_on_cpu]()
that behaves just like kthread_run(). kthread_create_worker[_on_cpu]()
will now only create a kthread worker without starting it.

When function of_find_device_by_node() fails, it returns NULL instead of
an error code. So the corresponding error check logic should be modified
to check whether the return value is NULL and set the error code to be
returned as -ENODEV.

In commit 4af65141e38e ("media: marvell: cafe: Register V4L2 device
earlier"), a call to v4l2_device_register() was moved away from
mccic_register() into its caller, marvell/cafe's cafe_pci_probe().
This is not the only caller though -- there's also marvell/mmp.
Add v4l2_device_register() into mmpcam_probe() to unbreak the MMP camera
driver, in a fashion analogous to what's been done to the Cafe driver.
Same for the teardown path.

This reverts commit cc1ecabe67d92a2da0b0402f715598e8dbdc3b9e.
This commit has a basic flaw in that it relies on camss->res->csid_num as a
control to index the array camss->vfe[i].
Testing on a platform where csid_num > vfe_num showed this bug up.
camss->vfe should only be indexed by camss->res->vfe_num. Since this commit
is meant to make the code be more readable reverting will simply restore
the previous correct bounds checking.
We can make another pass at making camss_link_entities look prettier but,
for now we should zap the bug introduced.

Add resource structure data and probe() logic to support static
declarations of encoder and decoder.
Right now we rely on video encoder/decoder selection happening in the dtb
but, this goes against the remit of device tree which is supposed to
describe hardware, not select functional logic in Linux drivers.
Provide two strings in the venus resource structure enc_nodename and
dec_nodename.
When set the venus driver will create an OF entry in-memory consistent
with:
dec_nodename {
compat = "video-decoder";
};
and/or
enc_nodename {
compat = "video-encoder";
};
This will allow us to reuse the existing driver scheme of relying on compat
names maintaining compatibility with old dtb files.
dec_nodename can be "video-decoder" or "video0"
enc_nodename can be "video-encoder" or "video1"
This change relies on of_changeset() API as a result select OF_DYNAMIC will
be added to venus/Kconfig

This partially reverts commit that made hfi_session_destroy()
the first step of vdec/venc close(). The reason being is a
regression report when, supposedly, encode/decoder is closed
with still active streaming (no ->stop_streaming() call before
close()) and pending pkts, so isr_thread cannot find instance
and fails to process those pending pkts. This was the idea
behind the original patch - make it impossible to use instance
under destruction, because this is racy, but apparently there
are uses cases that depend on that unsafe pattern. Return to
the old (unsafe) behaviour for the time being (until a better
fix is found).

The Unicam hardware has been observed to cause a buffer overrun when
using the dummy buffer as a circular buffer. The conditions that cause
the overrun are not fully known, but it seems to occur when the memory
bus is heavily loaded.
To avoid the overrun, program the hardware with a buffer size of 0 when
using the dummy buffer. This will cause overrun into the allocated dummy
buffer, but avoid out of bounds writes.

The imx219/imx708 sensors frequently generate a single corrupt frame
(image or embedded data) when the sensor first starts. This can either
be a missing line, or invalid samples within the line. This only occurrs
using the upstream Unicam kernel driver.
Disabling trigger mode elimiates this corruption. Since trigger mode is
a legacy feature copied from the firmware driver and not expected to be
needed, remove it. Tested on the Raspberry Pi cameras and shows no ill
effects.

With KASAN enabled, clang fails to optimize the inline version of
vdec_vp9_slice_map_counts_eob_coef() properly, leading to kilobytes
of temporary values spilled to the stack:

This seems to affect all versions of clang including the latest (clang-20),
but the degree of stack overhead is different per release.
Marking the function as noinline_for_stack is harmless here and avoids
the problem completely.

is passed to cmdq_pkt_write_mask(), effectively disregarding the mask
and calling cmdq_pkt_write() as an optimization.
Move that optimization to the MM_REG_WRITE_MASK macro and make
MM_REG_WRITE the variant that doesn't take a mask, directly calling to
cmdq_pkt_write().
Change the call sites to MM_REG_WRITE whenever a mask wasn't necessary
(ie 0xffffffff or a <register>_MASK was passed as mask) and in other
cases to MM_REG_WRITE_MASK.

cmdq_pkt_write_mask() boils down to a cmdq_pkt_write() when the mask is
0xFFFFFFFF. Call cmdq_pkt_write() directly in those cases to simplify
the code.

The stm32mp25 supports both parallel & csi inputs.
An additional clock control is necessary.
Skeleton of the subdev structures for the stm32mp25 is added,
identical for the time being to the stm32mp13 however more subdeves
will be added in further commits.

Avoid duplication of enumerated pixelformat on the bytecap
video capture device. Indeed, since the bytecap format list
contains both CSI & parallel 16bits formats, ensure that same
pixelformat are not reported twice when performing enumeration
of supported formats.

There apparently is no reason to require 3 queued buffers to call
streamon() for the RkISP1 as the driver operates with a scratch buffer
where frames can be directed to if there's no available buffer provided
by userspace.
Reduce the number of required buffers to 1 to allow applications to
operate with a single queued buffer.
Tested with libcamera, by operating with a single capture request. The
same request (and associated capture buffer) gets recycled once
completed. This of course causes a frame rate drop but doesn't hinder
operations.
