Add new ioctls to set and get subdev client capabilities. Client in this
context means the userspace application which opens the subdev device
node. The client capabilities are stored in the file handle of the
opened subdev device node, and the client must set the capabilities for
each opened subdev.
For now we only add a single flag, V4L2_SUBDEV_CLIENT_CAP_STREAMS, which
indicates that the client is streams-aware.
The reason for needing such a flag is as follows:
Many structs passed via ioctls, e.g. struct v4l2_subdev_format, contain
reserved fields (usually a single array field). These reserved fields
can be used to extend the ioctl. The userspace is required to zero the
reserved fields.
We recently added a new 'stream' field to many of these structs, and the
space for the field was taken from these reserved arrays. The assumption
was that these new 'stream' fields are always initialized to zero if the
userspace does not use them. This was a mistake, as, as mentioned above,
the userspace is required to zero the _reserved_ fields. In other words,
there is no requirement to zero this new stream field, and if the
userspace doesn't use the field (which is the case for all userspace
applications at the moment), the field may contain random data.
This shows that the way the reserved fields are defined in v4l2 is, in
my opinion, somewhat broken, but there is nothing to do about that.
To fix this issue we need a way for the userspace to tell the kernel
that the userspace has indeed set the 'stream' field, and it's fine for
the kernel to access it. This is achieved with the new ioctl, which the
userspace should usually use right after opening the subdev device node.

Several drivers call subdev pad operations, passing structures that are
not fully zeroed. While the drivers initialize the fields they care
about explicitly, this results in reserved fields having uninitialized
values. Future kernel API changes that make use of those fields thus
risk breaking proper driver operation in ways that could be hard to
detect.
To avoid this, make the code more robust by zero-initializing all the
structures passed to subdev pad operation. Maintain a consistent coding
style by preferring designated initializers (which zero-initialize all
the fields that are not specified) over memset() where possible, and
make variable declarations local to inner scopes where applicable. One
notable exception to this rule is in the ipu3 driver, where a memset()
is needed as the structure is not a local variable but a function
parameter provided by the caller.
Not all fields of those structures can be initialized when declaring the
variables, as the values for those fields are computed later in the
code. Initialize the 'which' field in all cases, and other fields when
the variable declaration is so close to the v4l2_subdev_call() call that
it keeps all the context easily visible when reading the code, to avoid
hindering readability.

compressed format") added support for the QC08C and QC10C compressed
formats respectively.
But these also caused a regression, because the new formats where added
at the beginning of the vdec_formats[] array and the vdec_inst_init()
function sets the default format output and capture using fixed indexes
of that array:
static void vdec_inst_init(struct venus_inst *inst)
{
...
inst->fmt_out = &vdec_formats[8];
inst->fmt_cap = &vdec_formats[0];
...
}
Since now V4L2_PIX_FMT_NV12 is not the first entry in the array anymore,
the default capture format is not set to that as it was done before.
Both commits changed the first index to keep inst->fmt_out default format
set to V4L2_PIX_FMT_H264, but did not update the latter to keep .fmt_out
default format set to V4L2_PIX_FMT_NV12.
Rather than updating the index to the current V4L2_PIX_FMT_NV12 position,
let's reorder the entries so that this format is the first entry again.
This would also make VIDIOC_ENUM_FMT report the V4L2_PIX_FMT_NV12 format
with an index 0 as it did before the QC08C and QC10C formats were added.

The "rotation" fwnode device property is intended to allow specify the

can decide how to compensate for that.
The imx258 driver has read-only VFLIP and HFLIP enabled, resulting in
a 180 degrees image rotation being produced by the sensor. But this
doesn't imply that the physical mounting rotation should match the
driver's implementation.
Now that the driver registers V4L2_CID_CAMERA_SENSOR_ROTATION

to require the 'rotation' property to be fixed to 180 degrees in DTS.
