commit eb2fd187abc878a2dfad46902becb74963473c7d upstream.
Add H264 level 1.0, 4.1, 4.2 to the list of supported formats.
While the hardware does not fully support these levels, it does support
most of them. The constraints on frame size and pixel formats already
cover the limitation.
This fixes negotiation of level on GStreamer 1.17.1.

commit 7110c08ea71953a7fc342f0b76046f72442cf26c upstream.
The CODA960 manual states that ASO/FMO features of baseline are not
supported, so for this reason this driver should only report
constrained baseline support.
This fixes negotiation issue with constrained baseline content
on GStreamer 1.17.1.
ASO/FMO features are unsupported for the encoder and untested for the
decoder because there is currently no userspace support. Neither GStreamer
parsers nor FFMPEG parsers support ASO/FMO.

The vertical subsampling factor is currently not considered in the
offset calculation for plane cropping done in rpf_configure_partition.
This causes a distortion (shift of the color plane) when formats with
the vsub factor larger than 1 are used (e.g. NV12, see
vsp1_video_formats in vsp1_pipe.c). This commit considers vsub factor
for all planes except plane 0 (luminance).

The list iterator will point to a bogus position containing HEAD if
the list is empty or the element is not found in list. This case
should be checked before any use of the iterator, otherwise it will
lead to a invalid memory access. The missing check here is before
"pin = iterm->id;", just add check here to fix the security bug.
In addition, the list iterator value will *always* be set and non-NULL
by list_for_each_entry(), so it is incorrect to assume that the iterator
value will be NULL if the element is not found in list, considering
the (mis)use here: "if (iterm == NULL".
Use a new value 'it' as the list iterator, while use the old value
'iterm' as a dedicated pointer to point to the found element, which
1. can fix this bug, due to 'iterm' is NULL only if it's not found.
2. do not need to change all the uses of 'iterm' after the loop.
3. can also limit the scope of the list iterator 'it' *only inside*
the traversal loop by simply declaring 'it' inside the loop in the
future, as usage of the iterator outside of the list_for_each_entry
is considered harmful. https://lkml.org/lkml/2022/2/17/1032

The 'maxim,gpio-poc' property is used when the remote camera
power-over-coax is controlled by one of the MAX9286 gpio lines,
to instruct the driver about which line to use and what the line
polarity is.
Add to the max9286 driver support for parsing the newly introduced
property and use it if available in place of the usual supply, as it is
not possible to establish one as consumer of the max9286 gpio
controller.
If the new property is present, no gpio controller is registered and
'poc-supply' is ignored.
In order to maximize code re-use, break out the max9286 gpio handling
function so that they can be used by the gpio controller through the
gpio-consumer API, or directly by the driver code.
Wrap the power up and power down routines to their own function to
be able to use either the gpio line directly or the supply. This will
make it easier to control the remote camera power at run time.

If an adapter is trying to claim a free logical address then it is
in the 'is_configuring' state. If during that process the cable is
disconnected (HPD goes low, which in turn invalidates the physical
address), then cec_adap_unconfigure() is called, and that set the
is_configuring boolean to false, even though the thread that's
trying to claim an LA is still running.
Don't touch the is_configuring bool in cec_adap_unconfigure(), it
will eventually be cleared by the thread. By making that change
the cec_config_log_addr() function also had to change: it was
aborting if is_configuring became false (since that is what
cec_adap_unconfigure() did), but that no longer works. Instead
check if the physical address is invalid. That is a much
more appropriate check anyway.
This fixes a bug where the the adapter could be disabled even
though the device was still configuring. This could cause POLL
transmits to time out.

Since usb_register_dev() from imon_init_display() from imon_probe() holds
minor_rwsem while display_open() which holds driver_lock and ictx->lock is
called with minor_rwsem held from usb_open(), holding driver_lock or
ictx->lock when calling usb_register_dev() causes circular locking
dependency problem.
Since usb_deregister_dev() from imon_disconnect() holds minor_rwsem while
display_open() which holds driver_lock is called with minor_rwsem held,
holding driver_lock when calling usb_deregister_dev() also causes circular
locking dependency problem.
Sean Young explained that the problem is there are imon devices which have
two usb interfaces, even though it is one device. The probe and disconnect
function of both usb interfaces can run concurrently.
Alan Stern responded that the driver and USB cores guarantee that when an
interface is probed, both the interface and its USB device are locked.
Ditto for when the disconnect callback gets run. So concurrent probing/
disconnection of multiple interfaces on the same device is not possible.
Therefore, we don't need locks for handling race between imon_probe() and
imon_disconnect(). But we still need to handle race between display_open()
/vfd_write()/lcd_write()/display_close() and imon_disconnect(), for
disconnect event can happen while file descriptors are in use.
Since "struct file"->private_data is set by display_open(), vfd_write()/
lcd_write()/display_close() can assume that "struct file"->private_data
is not NULL even after usb_set_intfdata(interface, NULL) was called.
Replace insufficiently held driver_lock with refcount_t based management.
Add a boolean flag for recording whether imon_disconnect() was already
called. Use RCU for accessing this boolean flag and refcount_t.
Since the boolean flag for imon_disconnect() is shared, disconnect event
on either intf0 or intf1 affects both interfaces. But I assume that this
change does not matter, for usually disconnect event would not happen
while interfaces are in use.

commit bb25f071fc92d3d227178a45853347c7b3b45a6b upstream.
The imx412/imx577 sensor has a reset line that is active low not active
high. Currently the logic for this is inverted.
The right way to define the reset line is to declare it active low in the
DTS and invert the logic currently contained in the driver.
The DTS should represent the hardware does i.e. reset is active low.
So:
+ reset-gpios = <&tlmm 78 GPIO_ACTIVE_LOW>;
not:
- reset-gpios = <&tlmm 78 GPIO_ACTIVE_HIGH>;
I was a bit reticent about changing this logic since I thought it might
negatively impact @intel.com users. Googling a bit though I believe this
sensor is used on "Keem Bay" which is clearly a DTS based system and is not
upstream yet.

they have been merged and reused as an implementation of .set_fmt() pad
operation by commit 717fd5b4907a ("[media] v4l2: replace try_mbus_fmt
by set_fmt").
Exclude non-compliant crop rectangle adjustments from set format try,
as well as a call to .set_selection() from set format active processing
path, so only frame scaling is applied as needed and crop rectangle is
no longer modified.

commit c74052646496ffe0bc606152e6b9653137020cbf upstream.
Try requests are now only supported by format processing pad operations
implemented by the driver. The driver selection API operations
currently respond to them with -EINVAL. While that is correct, it
constraints video device drivers to not use subdevice cropping at all
while processing user requested active frame size, otherwise their set
try format results might differ from active. As a consequence, we
can't fix set format pad operation as not to touch crop rectangle since
that would affect users not being able to set arbitrary frame sizes.
Moreover, without a working set try selection support we are not able
to use pad config crop rectangle as a reference while processing set
try format requests.
Implement missing try selection support. Moreover, as it will be now
possible to maintain the pad config crop rectangle via selection API,
start using it instead of the active one as a reference while
processing set try format requests.
is_unscaled_ok() helper, now also called from set selection operation,
has been just moved up in the source file to avoid a prototype, with no
functional changes.

ov5648_state_init() calls ov5648_state_mipi_configure() which uses
__v4l2_ctrl_s_ctrl[_int64](). This means that sensor->mutex (which
is also sensor->ctrls.handler.lock) must be locked before calling
ov5648_state_init().
ov5648_state_mipi_configure() is also used in other places where
the lock is already held so it cannot be changed itself.
Note this is based on an identical (tested) fix for the ov8865 driver,
this has only been compile-tested.

When error occurs in parsing jpeg, the slot isn't acquired yet, it may
be the default value MXC_MAX_SLOTS.
If the driver access the slot using the incorrect slot number, it will
access array out of bounds.
The result is the driver will change num_domains, which follows
slot_data in struct mxc_jpeg_dev.
Then the driver won't detach the pm domain at rmmod, which will lead to
kernel panic when trying to insmod again.

The ISC supports a full broad range of frame sizes.
Until now, the subdevice was queried for possible frame sizes and these
were reported to the user space.
However, the ISC should not care about which frame sizes the subdev
supports, as long as this frame size is supported.
Thus, report a continuous range from smallest frame size up to the max
resolution.

The VIDIOC_G_FBUF and related overlay ioctls no longer worked (-ENOTTY was
returned).
The root cause was the introduction of the caps field in ivtv-driver.h.
While loading the ivtvfb module would update the video_device device_caps
field with V4L2_CAP_VIDEO_OUTPUT_OVERLAY it would not update that caps
field, and that's what the overlay ioctls would look at.
It's a bad idea to keep information in two places, so drop the caps field
and only use vdev.device_caps.

In ov5640_set_fmt, pending_fmt_change will always be false, because the
sensor format is saved before comparing it with the previous format:
fmt = &sensor->fmt;...
*fmt = *mbus_fmt;...
if (mbus_fmt->code != sensor->fmt.code)
sensor->pending_fmt_change = true;
This causes the sensor to capture with the previous pixelcode.
Also, changes might happen even for V4L2_SUBDEV_FORMAT_TRY, so fix that.
Basically, revert back to the state before

not change, as resolution might change.

In the final H264 API, it is not required to set scaling matrix if
they are not present in the bitstream. A flag was added in order to let
the driver know. The downside is that it leaves the default control
value to 0, which isn't valid. As per the spec (see formulas 7-8/7-9),
when the scaling matrix are absent from the bitstream, flat values
of 16 should be used. This improves this control semantic in a way
that the control value are always valid. Drivers can then use
the scaling_matrix control values without having to check its presence.
Same method was employed for MPEG2_QUANTISATION.
This fixes issues with MTK VCODEC H264 decoder when using GStreamer.
GStreamer does not set this control if its not present in the bitstream.
As MTK VDCODEC was using the initialized to 0 values, the frames ended
up completely gray.
