0866df8dff [media] tvp5150: fix pad format frame height
Even if field order is set to V4L2_FIELD_ALTERNATE, the width and height
values in struct v4l2_mbus_framefmt still refer to frame size, not field
size.

f6f0e2f5d7 [media] tvp5150: allow get/set_fmt on the video source pad
To let userspace propagate formats downstream in a media controller
scenario, the video source pad (now pad 1, DEMOD_PAD_VID_OUT) must allow
setting and getting the format. Incidentally, tvp5150_fill_fmt was
implemented for this pad, not for the new analog input pad (now pad 0,
DEMOD_PAD_IF_INPUT).

678bc0adf7 [media] coda: remove redundant call to v4l2_m2m_get_vq
The call to v4ls_m2m_get_vq is only used to get the return value
which is not being used, so it appears to be redundant and can
be removed.

43c0c03961 [media] cec: Fix runtime BUG when (CONFIG_RC_CORE && !CEC_CAP_RC)
Currently when the RC Core is enabled (reachable) core code located
in cec_register_adapter() attempts to populate the RC structure with
a pointer to the 'parent' passed in by the caller.

Unfortunately if the caller did not specify RC capability when calling
cec_allocate_adapter(), then there will be no RC structure to populate.

This causes a "NULL pointer dereference" error.

6917a7b774 [media] media: add CEC notifier support
Add support for CEC notifiers, which is used to convey CEC physical address
information from video drivers to their CEC counterpart driver(s).

Based on an earlier version from Russell King:

https://patchwork.kernel.org/patch/9277043/

The cec_notifier is a reference counted object containing the CEC physical address
state of a video device.

When a new notifier is registered the current state will be reported to
that notifier at registration time.

4461c84b52 [media] v4l: vsp1: Prevent multiple streamon race commencing pipeline early
With multiple inputs through the BRU it is feasible for the streams to
race each other at stream-on.

Multiple VIDIOC_STREAMON calls racing each other could have process
N-1 skipping over the pipeline setup section and then start the pipeline
early, if videobuf2 has already enqueued buffers to the driver for
process N but not called the .start_streaming() operation yet

In the case of the video pipelines, this
can present two serious issues.

 1) A null-dereference if the pipe->dl is committed at the same time as
    the vsp1_video_setup_pipeline() is processing

 2) A hardware hang, where a display list is committed without having
    called vsp1_video_setup_pipeline() first

Repair this issue, by ensuring that only the stream which configures the
pipeline is able to start it.

NULL-pointer should a malicious device lack endpoints.

ba7ed691dc [media] v4l2-compat-ioctl32: VIDIOC_S_EDID should return all fields on error
Most ioctls do not have to write back the contents of the argument
if an error is returned. But VIDIOC_S_EDID is an exception together
with the EXT_CTRLS ioctls (already handled correctly).

Add this exception to v4l2-compat-ioctl32.

This fixes a compliance error when using compat32 and trying to
set a new EDID with more blocks than the hardware supports. In
that case the driver will return -E2BIG and set edid.blocks to the
actual maximum number of blocks. This field was never copied back
to userspace due to this bug.

51d979c0bb [media] vcodec: mediatek: mark pm functions as __maybe_unused
When CONFIG_PM is disabled, we get a couple of unused functions:

drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c:927:13: error: 'mtk_jpeg_clk_off' defined but not used [-Werror=unused-function]
 static void mtk_jpeg_clk_off(struct mtk_jpeg_dev *jpeg)
             ^~~~~~~~~~~~~~~~
drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c:916:13: error: 'mtk_jpeg_clk_on' defined but not used [-Werror=unused-function]
 static void mtk_jpeg_clk_on(struct mtk_jpeg_dev *jpeg)

Rather than adding more error-prone #ifdefs around those, this patch
removes the existing #ifdef checks and marks the PM functions as __maybe_unused
to let gcc do the right thing.

d251510d4c [media] s5p-mfc: Don't allocate codec buffers from pre-allocated region
Further investigation revealed that codec buffers also don't need to
be allocated at higher addresses than firmware base for MFC v6+ hardware.
Those buffers can be quite large and its size depends on the selected
format and framesize. This patch changes the way the codec buffers are
allocated - driver will use generic allocator for them instead of the
pre-allocated buffer for firmware and contexts.

Clock should be turned off after calling s5p_mfc_init_hw() from the
watchdog worker, like it is already done in the s5p_mfc_open() which also
calls this function.

60641e2259 [media] s5p-mfc: Use preallocated block allocator always for MFC v6+
It turned out that all versions of MFC v6+ hardware doesn't have a strict
requirement for ALL buffers to be allocated on higher addresses than the
firmware base like it was documented for MFC v5. This requirement is true
only for the device and per-context buffers. All video data buffers can be
allocated anywhere for all MFC v6+ versions. Basing on this fact, the
special DMA configuration based on two reserved memory regions is not
really needed for MFC v6+ devices, because the memory requirements for the
firmware, device and per-context buffers can be fulfilled by the simple
probe-time pre-allocated block allocator introduced in previous patch.

This patch enables support for such pre-allocated block based allocator
always for MFC v6+ devices. Due to the limitations of the memory management
subsystem the largest supported size of the pre-allocated buffer when no
CMA (Contiguous Memory Allocator) is enabled is 4 MiB.

This patch also removes the requirement to provide two reserved memory
regions for MFC v6+ devices in device tree. Now the driver is fully
functional without them.
