The v4l2_event structure contains a 'struct timespec' member that is
defined by the user space C library, creating an ABI incompatibility
when that gets updated to a 64-bit time_t.
While passing a 32-bit time_t here would be sufficient for CLOCK_MONOTONIC
timestamps, simply redefining the structure to use the kernel's
__kernel_old_timespec would not work for any library that uses a copy
of the linux/videodev2.h header file rather than including the copy from
the latest kernel headers.
This means the kernel has to be changed to handle both versions of the
structure layout on a 32-bit architecture. The easiest way to do this
is during the copy from/to user space.

As a preparation for adding 64-bit time_t support in the uapi,
change the drivers to no longer care about the format of the
timestamp field in struct v4l2_buffer.
The v4l2_timeval_to_ns() function is no longer needed in the
kernel after this, but there is userspace code relying on
it to be part of the uapi header.

When building with Clang + -Wtautological-constant-compare, several of
the ivtv and cx18 drivers warn along the lines of:
drivers/media/pci/cx18/cx18-driver.c:1005:21: warning: converting the
result of '<<' to a boolean always evaluates to true
[-Wtautological-constant-compare]
cx18_call_hw(cx, CX18_HW_GPIO_RESET_CTRL,
^
drivers/media/pci/cx18/cx18-cards.h:18:37: note: expanded from macro
'CX18_HW_GPIO_RESET_CTRL'
#define CX18_HW_GPIO_RESET_CTRL (1 << 6)
^
1 warning generated.
This warning happens because the shift operation is implicitly converted
to a boolean in v4l2_device_mask_call_all before being negated. This can
be solved by just comparing the mask result to 0 explicitly so that
there is no boolean conversion. The ultimate goal is to enable
-Wtautological-compare globally because there are several subwarnings
that would be helpful to have.
For visual consistency and avoidance of these warnings in the future,
all of the implicitly boolean conversions in the v4l2_device macros
are converted to explicit ones as well.

This introduces the required definitions for HEVC decoding support with
stateless VPUs. The controls associated to the HEVC slice format provide
the required meta-data for decoding slices extracted from the bitstream.
They are not exported to the public V4L2 API since reworking this API
will likely be needed for covering various use-cases and new hardware.
Multi-slice decoding is exposed as a valid decoding mode to match current
H.264 support but it is not yet implemented.
The interface comes with the following limitations:
* No custom quantization matrices (scaling lists);
* Support for a single temporal layer only;
* No slice entry point offsets support;
* No conformance window support;
* No VUI parameters support;
* No support for SPS extensions: range, multilayer, 3d, scc, 4 bits;
* No support for PPS extensions: range, multilayer, 3d, scc, 4 bits.

It is often useful to figure out if a pixel_format is either YUV or RGB
especially for driver who can perform the pixel encoding conversion.
Instead of having each driver implement its own "is_this_yuv/rgb"
function based on a restricted set of pixel value, it is better to do
this in centralized manner.
We therefore add a pixel_enc member to the v4l2_format_info structure to

It is possible for one HDMI connector to have multiple CEC adapters. The
typical real-world scenario is that where one adapter is used when the
device is in standby, and one that's better/smarter when the device is
powered up.
The cec-notifier changes were made with that in mind, but I missed that in
order to support this you need to tell cec_notifier_cec_adap_unregister()
which adapter you are unregistering from the notifier.
Add this additional argument. It is currently unused, but once all drivers
use this, the CEC core will be adapted for these use-cases.

The v4l2_async_notifier_add_fwnode_subdev() did not take a reference of
the added fwnode, relying on the caller to handle that instead, in essence
putting the fwnode to be added if there was an error.
As the reference is eventually released during the notifier cleanup, this
is not intuitive nor logical. Improve this by always getting a reference
when the function succeeds, and the caller releasing the reference when it
does not *itself* need it anymore.
Luckily, perhaps, there were just a handful of callers using the function.

In order to support multiple CEC devices for an HDMI connector,
and to support cec_connector_info, drivers should use either a
cec_notifier_conn_(un)register pair of functions (HDMI drivers)
or a cec_notifier_cec_adap_(un)register pair (CEC adapter drivers).
This replaces cec_notifier_get_conn/cec_notifier_put.
For CEC adapters it is also no longer needed to call cec_notifier_register,
cec_register_cec_notifier and cec_notifier_unregister. This is now
all handled internally by the new functions.

Define struct cec_connector_info in media/cec.h and define
CEC_CAP_CONNECTOR_INFO. In a later patch this will be moved to
uapi/linux/cec.h.
The CEC_CAP_CONNECTOR_INFO capability can be set by drivers, but
cec_allocate_adapter() will remove it again until the public API
for this can be enabled once all drm drivers wire this up correctly.
Also add the cec_fill_conn_info_from_drm and cec_s_conn_info functions,
which are needed by drm drivers to fill in the cec_connector info
based on a drm_connector.
The cec_notifier_(un)register and cec_register_cec_notifier
prototypes were moved from cec-notifier.h to cec.h since cec.h no longer
includes cec-notifier.h. These headers included each other before,
which caused various problems.
Due to these changes the seco-cec driver was changed as well: it
should include cec-notifier.h, not cec.h.

Correctness of format type (try or active) and pad number parameters
passed to subdevice operation callbacks is now verified only for IOCTL
calls. However, those callbacks are also used by drivers, e.g., V4L2
host interfaces.
Since both subdev_do_ioctl() and drivers are using v4l2_subdev_call()
macro while calling subdevice operations, move those parameter checks
from subdev_do_ioctl() to v4l2_subdev_call() so we can avoid taking care
of those checks inside drivers.
Define a wrapper function for each operation callback in scope, then
gather those wrappers in a static v4l2_subdev_ops structure so the
v4l2_subdev_call() macro can find them easy if provided.

As we did a major change on this file, let's take the moment
to cleanup several coding style issues on it.
This patch was partially done with the help of two tools:
./scripts/checkpatch.pl --fix-inplace --strict
astyle --indent=tab=8 --style=linux
But manually adjusted in order to fit our style.

In vb2_vmalloc_get_userptr() the framevector is created with the
'write' argument set to false when vb2_create_framevec() is called
for OUTPUT buffers. So the pages are marked as read-only.
However, userspace will write to these buffers since it will fill
in the data to output. Since get_userptr is only called if the userptr
of the queued buffer has changed since the last time that same buffer
was queued, this will fail when the buffer contents is updated and the
buffer is queued again.
E.g., userspace fills buffer 1 with the output video and queues it.
The first time get_userptr is called and the pages are grabbed and
pinned in memory and marked read-only. The second time buffer 1 is
filled with different video data and queued again. Since the userptr
hasn't changed the get_userptr() callback isn't called again. Since
the pages were marked as read-only the new contents isn't updated.
Just always call vb2_create_framevec() with FOLL_WRITE to always
allow writing to the buffers.
Using USERPTR streaming with OUTPUT devices is almost never done. And
when it is done it is via v4l2-compliance and a driver like vim2m. But
since v4l2-compliance doesn't actually inspect the capture buffer and
compare it to the original output buffer, this issue was never noticed.
But the vicodec driver actually needs to parse the bitstream in the
OUTPUT buffers and any errors there will be immediately noticed. So
this time v4l2-compliance failed the USERPTR streaming test.

This commit adds pin to pad mapping and output format configuration support
in CX2584x-series chips to cx25840 driver.
This functionality is then used to allow disabling ivtv-specific hacks and
configuration values (called a "generic mode"), so cx25840 driver can be
used for other devices not needing them without risking compatibility
problems.

cx25840_load_fw() does the same thing as cx25840_reset(), only keeps
"is_initialized" flag so any further invocation of this function besides
the first one is a NOP.
Let's just call cx25840_reset() directly from cx25840_load_fw() instead of
open coding it there.
While we are at it, let's also improve comments about cx25840_load_fw()
so they are current and in the proper style (one of them even referred to a
non-existing cx25840 init operation).

Pull drm updates from Dave Airlie:
"This has two exciting community drivers for ARM Mali accelerators.
Since ARM has never been open source friendly on the GPU side of the
house, the community has had to create open source drivers for the
Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
series. Well done to all involved and hopefully this will help ARM
head in the right direction.
There is also now the ability if you don't have any of the legacy
drivers enabled (pre-KMS) to remove all the pre-KMS support code from
the core drm, this saves 10% or so in codesize on my machine.
i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
moves out of staging.

Calling VIDIOC_DQBUF can release the core serialization lock pointed to
by vb2_queue->lock if it has to wait for a new buffer to arrive.
However, if userspace dup()ped the video device filehandle, then it is
possible to read or call DQBUF from two filehandles at the same time.
It is also possible to call REQBUFS from one filehandle while the other
is waiting for a buffer. This will remove all the buffers and reallocate
new ones. Removing all the buffers isn't the problem here (that's already
handled correctly by DQBUF), but the reallocating part is: DQBUF isn't
aware that the buffers have changed.
This is fixed by setting a flag whenever the lock is released while waiting
for a buffer to arrive. And checking the flag where needed so we can return
-EBUSY.

Media Device Allocator API to allows multiple drivers share a media device.
This API solves a very common use-case for media devices where one physical
device (an USB stick) provides both audio and video. When such media device
exposes a standard USB Audio class, a proprietary Video class, two or more
independent drivers will share a single physical USB bridge. In such cases,
it is necessary to coordinate access to the shared resource.
Using this API, drivers can allocate a media device with the shared struct
device as the key. Once the media device is allocated by a driver, other
drivers can get a reference to it. The media device is released when all
the references are released.

If requests are used when they shouldn't, or not used when they should,
then return EBADR (Invalid request descriptor) instead of EACCES.
The reason for this change is that EACCES has more to do with permissions
(not being the owner of the resource), but in this case the request file
descriptor is just wrong for the current mode of the device.
Update the documentation accordingly.

Stateless codecs require the use of the Request API as opposed of it
being optional.
So add a bit to indicate this and let vb2 check for this.
If an attempt is made to queue a buffer without an associated request,
then the EBADR error is returned to userspace.
Doing this check in the vb2 core simplifies drivers, since they
don't have to check for this, they can just set this flag.
