media: Zero-initialize all structures passed to subdev pad operations
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.

media: venus: dec: Fix capture formats enumeration order
Commit
9593126dae3e ("media: venus: Add a handling of QC08C compressed
format") and commit
cef92b14e653 ("media: venus: Add a handling of QC10C
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.

media: imx258: Remove mandatory 180 degrees rotation
The "rotation" fwnode device property is intended to allow specify the
sensor's physical mounting rotation, so that it can be exposed through
the read-only V4L2_CID_CAMERA_SENSOR_ROTATION control and applications
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
and V4L2_CID_HFLIP/VFLIP correctly, userspace has all the required
information to handle the rotation correctly, hence it is not necessary
to require the 'rotation' property to be fixed to 180 degrees in DTS.

media: i2c: adv7604: Fix range of hue control
The ADV7604, ADV7611 and ADV7612 software manuals document the CP_HUE
value differently:
- For ADV7604 and ADV7611, the hue is specified as an unsigned 8-bit
value, and calculated as
(CP_HUE[7:0] * 180) / 256 - 90
with the range set to [-90°, 90°]. Additionally, the values 0x00, 0x0f
and 0xff are documented as corresponding to -90°, 0° and 90°
respectively.
- For ADV7612, the hue is specified as a signed 8-bit value in the range
[0°, 360°[ without any formula. Additionally, the value 0x00 is
documented as corresponding to 0°.
The ADV7604 and ADV7611 documentation is clearly wrong as the example
values don't correspond to the formula. Furthermore, the [-90°, 90°]
range seems incorrect as it would cover only half of the hue space.
The ADV7612 documentation is better, although the range should likely be
[-180°, 180°[ if the value is signed. Given that the values wrap around,
this makes no difference in practice.
The hue values have been verified on ADV7612 to follow the
documentation. There is a high chance they do as well on ADV7604 and
ADV7611.
In any case, all software manuals document the register as 8-bit, so the
current range of the V4L2 hue control [0, 128] is not correct. Expand it
to cover the full 8-bit space, using unsigned values to avoid breaking
any application that may rely on 128 being a valid value.

media: vsp1: Replace vb2_is_streaming() with vb2_start_streaming_called()
The vsp1 driver uses the vb2_is_streaming() function in its .buf_queue()
handler to check if the .start_streaming() operation has been called,
and decide whether to just add the buffer to an internal queue, or also
trigger a hardware run. vb2_is_streaming() relies on the vb2_queue
structure's streaming field, which used to be set only after calling the
.start_streaming() operation.
Commit
a10b21532574 ("media: vb2: add (un)prepare_streaming queue ops")
changed this, setting the .streaming field in vb2_core_streamon() before
enqueuing buffers to the driver and calling .start_streaming(). This
broke the vsp1 driver which now believes that .start_streaming() has
been called when it hasn't, leading to a crash:

A different regression report sent to the linux-media mailing list ([1])
was answered with a claim that the vb2_is_streaming() function has never
been meant for this purpose. The document of the function, as well as of
the struct vb2_queue streaming field, is sparse, so this claim may be
hard to verify.
The information needed by the vsp1 driver to decide how to process
queued buffers is also available from the vb2_start_streaming_called()
function. Use it instead of vb2_is_streaming() to fix the problem.

media: platform: mtk-mdp3: decompose hardware-related information in shared memory
The communication between the MDP3 kernel driver and SCP is to
pass a shared memory through the cooperation of "mtk-mdp3-vpu.c" and
remoteproc driver.
The data structure of this shared memory is defined in "mtk-img-ipi.h",
as shown below:
vpu->work_addr -> +-----------------------------------------+
| |
| To SCP : Input frame parameters |
| (struct img_ipi_frameparam) |

| *struct img_config N |
| (N = MDP_CONFIG_POOL_SIZE) |
+-----------------------------------------+
One output component configuration contains the components
currently used by the pipeline, and has the register settings
that each component needs to set.
Since the quantity, type and function of components on each chip
will vary, the effect is that the size of the "struct img_config"
and its substructures will be different on each chip.
In addition, all chips will have to update their SCP firmware for
every change if the output component config structure is defined
and shared by a common header.
Therefore, all functions that operate on "struct img_config" and
its substructures must be separated by chips and so are the
relevant definations.

According to commit
7945f929f1a7 ("drivers: provide
devm_platform_ioremap_resource()"), convert platform_get_resource(),
devm_ioremap_resource() to a single call to use
devm_platform_ioremap_resource(), as this is exactly what this function
does.

If the pattern generator is enabled the device shall not be queried for
timings. Instead the timings programmed shall be reported as they are
the ones being used to generate the pattern.
Before this change an external HDMI source needed to be connected for
the pattern generator to work. The driver would query this external
HDMI source for timings and program the pattern generator using those.
With this change the user can control the timings and have the pattern
generator work without the need of an external HDMI source being
connected.

media: i2c: adv748x: Write initial DV timings to device
When initializing the HDMI block during probe an initial set of timings
are selected. These timings are stored in the drivers private data, but
not written to the device.
This in itself is not bad, but in s_dv_timings() the timings stored in
the drivers private data are compared to the new timings, if they match
no action is taken. This creates the corner-case where the timing
selected at initialization is the first timings a user want to use as
the driver then never writes it to the device preventing proper
operation.
Fix this by writing the timings to the device at initialization in
addition to storing them in the drivers private data.

The loop to match the requested timings with the ones supported by the
driver is incorrect. It always iterates thru the whole array of
supported modes. The bounds check after the loop always triggers
resulting in adv748x_hdmi_set_video_timings() always returning -EINVAL.
Fix this by correcting the lookup to break the loop when a match is

media: camss: sm8250: Pipeline starting and stopping for multiple virtual channels
Use the multistream series function video_device_pipeline_alloc_start
to allows multiple clients of the same pipeline.
If the VFE entity is used by another instance of the pipeline,
the pipeline won't be stopped. This allows for stopping and starting
streams at any point without disrupting the other running streams.
To prepare and start multiple virtual channels each CSID source pad
corresponding to a virtual channel must be linked to the corresponding
IFE entity. CSID pad 1 (1st source pad) corresponds to virtual
channel 0, CSID pad 2 corresponds to virtual channel 1 and so on.
Each of these must be linked to corresponding IFE RDI port.
E.g. to enable vc 0 on CSID0:
media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
To enable vc1 on CSID0:
media-ctl -l '"msm_csid0":2->"msm_vfe0_rdi1":0[1]'
And so on. Note that on SM8250 each CSID is connected, at the
hardware level, to only one IFE. Thus, you must link CSID0
with IFE0, you can't link it with IFE1.
Example: the following media controller setup expects multiplexed
sensor data on CSIPHY2. Data will be passed on to CSID0, which will
demux it to 2 streams - for RDI0 and RD1 ports of IFE0:
media-ctl -v -d /dev/media0 -V '"imx577 '22-001a'":0[fmt:SRGGB10/3840x2160 field:none]'
media-ctl -V '"msm_csiphy2":0[fmt:SRGGB10/3840x2160]'
media-ctl -V '"msm_csid0":0[fmt:SRGGB10/3840x2160]'
media-ctl -V '"msm_csid0":1[fmt:SRGGB10/3840x2160]'
media-ctl -V '"msm_csid0":2[fmt:SRGGB10/3840x2160]'
media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/3840x2160]'
media-ctl -V '"msm_vfe0_rdi1":0[fmt:SRGGB10/3840x2160]'
media-ctl -l '"msm_csiphy2":1->"msm_csid0":0[1]'
media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
media-ctl -l '"msm_csid0":2->"msm_vfe0_rdi1":0[1]'
Note: CSID's entity pad 0 is a sink pad, pads 1..4 are source pads
To start streaming a v4l2 client must open the corresponding
/dev/videoN node. For example, with yavta:
yavta -B capture-mplane -c -I -n 5 -f SRGGB10P -s 3840x2160 -F /dev/video0
yavta -B capture-mplane -c -I -n 5 -f SRGGB10P -s 3840x2160 -F /dev/video1
Note that IFEs (vfe0, vfe1) on SM8250 have 3 RDI ports and a single
PIX port and IFELites (vfe2, vfe3) have 4 RDI ports and no PIX port.

media: camss: sm8250: Virtual channels for CSID
CSID hardware on SM8250 can demux up to 4 simultaneous streams
based on virtual channel (vc) or datatype (dt).
The CSID subdevice entity now has 4 source ports that can be
enabled/disabled and thus can control which virtual channels
are enabled. Datatype demuxing not tested.
In order to keep a valid internal state of the subdevice,
implicit format propagation from the sink to the source pads
has been preserved. However, the format on each source pad
can be different and in that case it must be configured explicitly.
CSID's s_stream is called when any stream is started or stopped.
It will call configure_streams() that will rewrite IRQ settings to HW.
When multiple streams are running simultaneously there is an issue
when writing IRQ settings for one stream while another is still
running, thus avoid re-writing settings if they were not changed
in link setup, or by fully powering off the CSID hardware.
