The YUV24 format is missing an entry in the v4l2_format_info().
The YUV24 format is the packed YUV 4:4:4 formats with 8 bits
per component.
Fixes: 0376a51fbe5e ("media: v4l: Add packed YUV444 24bpp pixel format")

+ The Chips&Media Wave6 codec IP is a multi-standard video encoder/decoder.
+ On NXP i.MX SoCs, Wave6 codec IP functionality is split between
+ the VPU control region and the VPU core region.
+ The VPU control region manages shared resources such as firmware memory,
+ while the VPU core region provides encoding and decoding

Pretty incomplete commit msg. Nothing explaining hardware, nothing

Why do you need here compatible? Can this child be anything else? Can it
be re-used? Is it actually a separate block?
Your example suggests that the only distinctive resource are the
interrupt and address space and that's on the edge of calling it a
separate device.
There is some tendency to call such "pseudo-cores" a separate devices in
case of video codec bindings and experience shows these are usually
fake. It's not the same as DP or HDMI sub-block of display pipeline.
That's why you should come here with strong argument what separate piece
of hardware this is.

Thanks for your feedback.
As you mentioned, I wanted to represent the interrupts and address space
as separate "cores". This is because, from an external perspective (e.g. multi-VM),
each of these resources is a VPU interface and can be accessed independently
to operate the VPU.
However, there is indeed only one actual VPU processing engine.
I understand your point about "pseudo-cores".
I would appreciate any guidance on the preferred way to represent
these resources in the device tree.

Apologies, I forgot to mention one detail in my previous reply.
I did not include the SMMU-related properties in the core nodes.
On this SoC, however, each of these cores has its own SMMU ID
as part of the SoC's isolation policy.
This allows them to be treated as independent interfaces,
even though there is only one actual VPU engine.
Would adding the iommu property be the appropriate way to describe
this in the device tree?
Thanks,
Nas.

This adds the interface layer to manage hardware register configuration
and communication with the Chips&Media Wave6 video codec IP.
The interface provides low-level helper functions used by the
Wave6 core driver to implement video encoding and decoding operations.
It handles command submission to the firmware via MMIO registers,
and waits for a response by polling the firmware busy flag.

This adds v4l2 m2m stateful driver support for the
Chips&Media Wave6 video codec IP, including both encoder and decoder.
The following features and formats are supported:
Encoder (8bit only):
- Supported codecs: AVC, HEVC
- Supported input formats:
* V4L2_PIX_FMT_YUV420/NV12/NV21
* V4L2_PIX_FMT_YUV422P/NV16/NV61
* V4L2_PIX_FMT_YUYV
* V4L2_PIX_FMT_YUV24/NV24/NV42
* V4L2_PIX_FMT_RGB24
* V4L2_PIX_FMT_P010
* V4L2_PIX_FMT_ARGB32
* V4L2_PIX_FMT_RGBA32
* V4L2_PIX_FMT_XRGB32
* V4L2_PIX_FMT_ARGB2101010
- Supports multiplanar format
- Although 10-bit input formats are supported (e.g., P010, ARGB2101010),
encoded output is limited to 8-bit streams
- Supports crop
- Supports extensive v4l2 encoder control
Decoder (8bit only):
- Supported codecs: AVC, HEVC (8bit only)
- Supported output formats: V4L2_PIX_FMT_YUV420/NV12/NV21
- Supports multiplanar format
- Supports scale down
- Supports dynamic resolution change
Note: While other versions of the Wave6 IP may support VP9 decoding and
AV1 decoding and encoding those formats are not implemented or validated
in this driver at this time.

This adds the core driver for the Chips&Media Wave6 video codec IP.
The core region provides the encoding and decoding capabilities of
the VPU and depends on the control region for firmware and shared
resource management.
This driver configure the v4l2 m2m video device and handles
communication with the Wave6 hardware to perform video processing tasks.

This adds debugfs entries and trace events to provide detailed
debugging information.
These enhancements help diagnose issues and improve debugging
capabilities for the Wave6 core driver.

This adds a thermal cooling device for the Wave6 VPU.
The device operates within the Linux thermal framework,
adjusting the VPU performance state based on thermal conditions.

This adds the control driver for the Chips&Media Wave6 video codec IP.
On NXP i.MX platforms, the Wave6 consists of two functional regions:
a control region responsible for firmware and shared resources,
and a core region for encoding and decoding.
The control driver manages shared resources such as firmware loading,
firmware memory allocation, and synchronization required by the core.
It also binds the `wave6-core` sub-device and coordinates with it
for firmware and power state management.

+ Chips&Media Wave6 stateful codec driver.
+ The wave6 driver manages shared resources such as firmware memory.
+ The wave6-core driver provides encoding and decoding capabilities
+ for H.264, HEVC, and other video formats.
+ To compile this driver as modules, choose M here: the
+ modules will be called wave6 and wave6-core.

This callback is called asynchronously via firmware_request_nowait_nowarn().
In practice, I observed a case where the callback was executing
while the device's release() function was being called.

Indeed. Now I wonder how does it protect from concurrent remove()?
