When an program is streaming (ffplay) and another program (qv4l2)
changes the TV standard from NTSC to PAL, the kernel crashes due to trying
to copy to unmapped memory.
Changing from NTSC to PAL increases the resolution in the usbtv struct,
but the video plane buffer isn't adjusted, so it overflows.

Complete the conversion from soc_camera to a full fledge media
controller enabled devices for all supported generations of the device.
All work is already done as this is already supported on Gen3, and
later.
All that is missing is removing all special cases for the non
media-graph call paths and use the common ones in their place.
The one change that stands out is dropping the doubling of the height in
the Gen2 scaler setup, rvin_scaler_gen2(). In the Gen2 non-MC world the
VIN size was set to match the video source subdevices, and if that was a
TOP/BOTTOM video source it needed to be doubled for the scaler to
function properly. In the MC world this is now handled by user-space
configuration of the pipeline and the adjustment is not needed.

The VIN usage of v4l-async is complex and stems from organic growth of
the driver of supporting both private local subdevices (Gen2, Gen3) and
subdevices shared between all VIN instances (Gen3 and Gen4).
The driver used a separate notifier for each VIN for the private local
ones, and a shared group notifier for the shared ones. This was complex
and lead to subtle bugs when unbinding and later rebinding subdevices in
one of the notifiers having to handle different edge cases depending on
if it also had subdevices in the other notifiers etc.
To simplify this have the Gen2 devices allocate and form a VIN group
too. This way all subdevices on all models can be collect in a
single group notifier. Then there is only a single complete callback for
all where the video devices and subdevice nodes can be registered etc.

To implement VIDIOC_QUERYCTRL, we need to know the minimum, maximum,
step and flags of the control. For some of the controls, this involves
querying the actual hardware.
Some non-compliant cameras produce errors when we query them. These
error can be triggered every time, sometimes, or when other controls do
not have the "right value". Right now, we populate that error to userspace.
When an error happens, the v4l2 framework does not copy the v4l2_queryctrl
struct to userspace. Also, userspace apps are not ready to handle any
other error than -EINVAL.
One of the main usecases of VIDIOC_QUERYCTRL is enumerating the controls
of a device. This is done using the V4L2_CTRL_FLAG_NEXT_CTRL flag. In
that usecase, a non-compliant control will make it almost impossible to
enumerate all controls of the device.
A control with an invalid max/min/step/flags is better than non being
able to enumerate the rest of the controls.
This patch:
- Retries for an extra attempt to read the control, to avoid spurious
errors. More attempts do not seem to produce better results in the
tested hardware.
- Makes VIDIOC_QUERYCTRL return 0 for -EIO errors.
- Introduces a warning in dmesg so we can have a trace of what has happened
and sets the V4L2_CTRL_FLAG_DISABLED.
- Makes sure we keep returning V4L2_CTRL_FLAG_DISABLED for all the next
attempts to query that control (other operations have the same
functionality as now).

Some I2C ATRs do not support dynamic remapping, only static mapping
of direct children.
Mappings will only be added or removed as a result of devices being
added or removed from a child bus.
The ATR pool will have to be big enough to accommodate all devices
expected to be added to the child buses.
Add a new flag that prevents old mappings to be replaced or new mappings
to be created in the alias finding code paths. That mens adding a flags
parameter to i2c_atr_new() and an i2c_atr_flags enum.

During initialization, the post processor allocates the same number of
buffers as the buf queue.
As the init function is called in streamon(), if an allocation fails,
streamon will return an error and streamoff() will not be called, keeping
all post processor buffers allocated.
To avoid that, all post proc buffers are freed in case of an allocation
error.

The kernel test robot reports the following error when building on
Hexagon with hexagon-allmodconfig.
ERROR: modpost: "__hexagon_divdi3"
[drivers/media/platform/amlogic/c3/mipi-csi2/c3-mipi-csi2.ko] undefined!
The error is caused by using DIV_ROUND_UP() with a 64 bits divisor with
a 32-bit dividend, which on Hexagon and clang-17 is resolved with a call
to the __hexagon_divdi3() helper function, part of the compiler support
library and not available when building Linux.
Use DIV_ROUND_UP_ULL() to fix the build error and avoid calling the
__hexagon_divdi3() helper function.

uvc_gpio_parse() can return -EPROBE_DEFER when the GPIOs it depends on
have not yet been probed. This return code should be propagated to the
caller of uvc_probe() to ensure that probing is retried when the required
GPIOs become available.
Currently, this error code is incorrectly converted to -ENODEV,
causing some internal cameras to be ignored.
This commit fixes this issue by propagating the -EPROBE_DEFER error.

Now that every ioctl takes care of their power management we can remove
the "global" power management.
Despite its size, this is a relatively big change. We hope that there
are no size effects of it. If there are some specific devices that
miss-behave, we can add a small quirk for them.
This patch introduces a behavioral change for the uvc "trigger" button.
Before the "trigger" button would work as long as userspace has opened
/dev/videoX. Now it only works when the camera is actually streaming. We
consider that this the most common (if not the only) usecase and
therefore we do not think of this as a regression.

Now we call uvc_pm_get/put from the device open/close. This low
level of granularity might leave the camera powered on in situations
where it is not needed.
Increase the granularity by increasing and decreasing the Power
Management counter per ioctl. There are two special cases where the
power management outlives the ioctl: async controls and streamon. Handle
those cases as well.
In a future patch, we will remove the uvc_pm_get/put from open/close.

This incorrectly extended the frame size enumeration to check against
the supported mbus_codes array instead of the supported mode/frame

Fix the check accordingly to report a frame size for each supported

hardcodes the colorspace field on all video devices and subdevices to
V4L2_COLORSPACE_SRGB, regardless of the configured format. The
xfer_func, ycbcr_enc and quantization fields are not set (except for
hsv_enc for HSV formats on video devices). This doesn't match the
hardware configuration, which handles YUV data as encoding in BT.601
with limited range.
As a first step towards colour space configuration, keep the colour
space fields hardcoded, but set them based on the selected format type
(RGB, YUV or HSV).

When the RPF/WPF units are used for ISP interfacing through
the IIF, the set of accessible registers is limited compared to
the regular VSPD operations.
Support ISP interfacing in the rpf and wpf entities by checking if
the pipe features an IIF instance and writing only the relevant
registers.

vsp1_wpf.c calls vsp1_rwpf_init_ctrls() to initialize controls that
are common between RPF and WPF.
However, the vsp1_wpf.c implementation does not check for the function
call return value. Fix this by propagating to the caller the return
value.
While at it, drop a duplicated error message in wpf_init_controls() as
the caller already report it.

The vsp1_dl library allows to program a display list and feed it
continuously to the VSP2. As an alternative operation mode, the library
allows to program the VSP2 in 'single shot' mode, where a display list
is submitted to the VSP on request only.
Currently the 'single shot' mode is only available when the VSP2 is
controlled by userspace, while it works in continuous mode when driven
by DRM, as frames have to be submitted to the display continuously.
For the VSPX use case, where there is no uapi support, we should however
work in single-shot mode as the ISP driver programs the VSPX on
request.
Initialize the display lists in single shot mode in case the VSP1 is
controlled by userspace or in case the pipeline features an IIF entity,
as in the VSPX case.

pcim_iomap_regions(), furthermore, has so far wrongly been passed the

When output encoded buffer size provided by userspace
is insufficient with current encoding parameters, it
leads to RET_ENC_BUFFER_FULL interrupt which was not
handled in IRQ handler.
On handling of RET_ENC_BUFFER_FULL interrupt leads to
NAL_ABORT command from host to risc which in turn leads
to RET_NAL_ABORT interrupt. On receiving RET_NAL_ABORT
driver clears workbit and VB2 queues for cleaner closing
of MFC instance.
When user encounters "Call on DQBUF after unrecoverable
error", userspace should close fd and restart with larger
output encoder buffer size.

pm_runtime_suspended() only checks the current runtime PM status and does
not modify it, making it ineffective in this context. This could result in
improper power management if the device remains active when removed.
This patch fixes the issue by introducing a check with
pm_runtime_status_suspended() to determine if the device is already
suspended. If it is not, it calls imx334_power_off() to power down the
device and then uses pm_runtime_set_suspended() to correctly update the
runtime PM status to suspended.

The I²C retry hack has been there in order to address transient I²C
register write access issues on a few very old sensors and possibly it has
addressed also first I²C access problems (device not responding until a
certain amount of time has passed) but that is now separately handled. The
retry hack has a good potential for introducing hard to debug problems in

When shutting down capture extra care was needed to try and complete a
buffer that was involved in the emulated support for SEQ_{TB,BT}. This
was needed as a buffer might be queued once to the driver, but two times
to the hardware using different offsets.
As support for SEQ_{TB,BT} is now removed this shutdown process can be
greatly simplified. And in addition the state keeping of the VIN device
can be reduced to a single boolean value instead of keeping track of
this SEQ_{TB,BT} stopping dance.

The STARTING state is superfluous and can be replaced with a check of
the sequence counter. The design idea is that the first buffer returned
from the driver have to come from the first hardware buffer slot.
Failing this the first 3 buffers queued to the device can be returned
out-of-order.
But it's much clearer to check the sequence counter to only return the
first buffer if it comes from hardware slot 0 then it is to carry around
an extra state just for this. Remove the unneeded state and replace it
with a simpler check.

The VIN state of suspended is superfluous. The logic was that when the
device were suspended and in a RUNNING state the state was set to
SUSPENDED. And when resuming it checked if the state is SUSPENDED and if
so started the device and changed it to RUNNING.
This can be avoided by simply checking if the device is in a RUNNING
state at both suspend and resume callbacks. Remove the unneeded
complexity.

When the driver was converted from soc_camera software support for
V4L2_FIELD_SEQ_TB and V4L2_FIELD_SEQ_BT were added. This was done by
capturing twice to the same VB2 buffer, but at different offsets.
This turned out to be a bad idea and it never really worked properly in
all situations. As the hardware can't support this mode natively remove
trying to emulate it in software. It's still possible to capture TOP or
BOTTOM fields separately or both ALTERNATING. If user-space wants the
same fields in the same buffer the same hack to capture twice to the
same buffer can be done.
Removing this error prone emulated support pave ways in future work to
simplify the internal buffer handling and making it less fragile, while
enabling adding support for other features the hardware actually
supports.

Add multiplexed streams support. CAL has 8 DMA-engines and can capture 8
separate streams at the same time. The driver filters the streams based
on CSI-2 virtual channel number and datatype. CAL may have (depending on
the SoC) two CSI-2 RX blocks, which share the 8 DMA-engines, so the
number of capturable streams does not change even if there are two CSI-2
RX blocks.
Add 8 video device nodes, each representing a single DMA-engine, and set
the number of source pads on CSI-2 RX blocks to 8. Each video node can be
connected to any of the source pads on either of the CSI-2 RX instances
using media links. CSI-2 RX block's subdevice internal routing is used
to route the incoming CSI-2 streams to one of the 8 source pads.
Only video data streams are supported at the moment.

For continuous PLL lock, it is recommended to extend the temperature
ramp down range of the DS90UB953-Q1 serializer based on the device's
initial temperature [1].
The serializer's die temperature is reported only to the deserializer
through the sensor status registers, and for UB9702, it is recommended
to set the temperature ramp during the link setup sequence, i.e. before
we even probe the ub953 driver.
Add support to the deserializer driver to configure ub953's temperature
ramp.

The driver does a lot of iteration over the RX ports with for loops. In
most cases the driver will skip unused RX ports. Also, in the future
patches the FPD-Link IV support will be refreshed with TI's latest init
sequences which involves a lot of additional iterations over the RX
ports, often only for FPD-Link IV ports.
To make the iteration simpler and to make it clearer what we're
iterating over (all or only-active, all or only-fpd4), add macros and
support functions for iterating the RX ports. Use the macros in the

As the first frame in "repeat-mode" is the pattern, the pattern done
interrupt is ignored by the driver. With small resolution bitstreams,
the interrupts might fire too quickly and hardware combine two irqs to
once because irq handle have latency. Thus the driver might miss the
frame decode done interrupt from the first actual frame.
In order to avoid the driver wait for the frame done interrupt that has
been combined to the pattern done interrupt and been ignored, driver
will check the curr_desc and slot_status registers to figure out if the
decoding of actual frame is finished or not.
Firstly we check the curr_desc register,
- if it is still pointing to the pattern descriptor, the second actual
frame is not started, we can wait for its frame-done interrupt.
- if the curr_desc has pointed to the frame descriptor, then we check the
ongoing bit of slot_status register.
- if the ongoing bit is set to 1, the decoding of the actual frame is not
finished, we can wait for its frame-done interrupt.
- if the ongoing bit is set to 0, the decoding of the actual frame is
finished, we can't wait for the second interrupt, but mark it as done.
But there is still a small problem, that the curr_desc and slot_status
registers are not synchronous. curr_desc is updated when the
next_descpt_ptr is loaded, but the ongoing bit of slot_status is set
after the 32 bytes descriptor is loaded, there will be a short time
interval in between, which may cause fake false. Consider read register
is quite slow compared with IP read 32byte from memory, read twice
slot_status can avoid this situation.

In order to decode a motion-jpeg bitstream, which doesn't provide a DHT,
the driver will first decode a pattern jpeg and use the DHT found in the
pattern to decode the first actual frame. This mode is called
"repeat-mode" and it utilizes linked descriptors.
The smallest supported resolution of 64x64 was used for that pattern to
not cause unneeded performance delay. This choice, however, can cause a
corrupted decoded picture of the first frame after the pattern, when the
resolution of that frame is larger than the pattern and is not aligned
to 64.
By altering the pattern size to 128x64, this corruption can be avoided.
That size has been confirmed to be safe by the hardware designers.
Additionally, a DMA buffer needs to be allocated to store the decoded
picture of the pattern image.
