ivtv: fix incorrect device_caps for ivtvfb
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.

media: i2c: max2175: Use rbtree rather than flat register cache
The max2175 uses a flat register cache but supplies only a single default
value and has many volatile registers. This is a poor fit for a flat cache
since the cache will assume a default of zero for any register not yet
written which can lead to bugs for example when regmap_update_bits()
suppresses a noop write. A rbtree cache is a much better fit, this will
only cache default values and values that have been written to the device
with any reads of uncached values going to the hardware. Convert the driver
to use a rbtree cache.
Since the device is controlled via I2C the cost of manging the rbtree
should be immaterial compared to the cost of accessing the device.

media: media-entity: Simplify media_pipeline_start()
The media_pipeline_start() function has two purposes: it constructs a
pipeline by recording the entities that are part of it, gathered from a
graph walk, and validate the media links. The pipeline pointer is stored
in the media_entity structure as part of this process, and the entity's
stream count is increased, to record that the entity is streaming.
When multiple video nodes are present in a pipeline,
media_pipeline_start() is typically called on all of them, with the same
pipeline pointer. This is taken into account in media_pipeline_start()
by skipping validation for entities that are already part of the
pipeline, while returning an error if an entity is part of a different
pipeline.
It turns out that this process is overly complicated. When
media_pipeline_start() is called for the first time, it constructs the
full pipeline, adding all entities and validating all the links.
Subsequent calls to media_pipeline_start() are then nearly no-ops, they
only increase the stream count on the pipeline and on all entities.
The media_entity stream_count field is used for two purposes: checking
if the entity is streaming, and detecting when a call to
media_pipeline_stop() balances needs to reset the entity pipe pointer to
NULL. The former can easily be replaced by a check of the pipe pointer.
Simplify media_pipeline_start() by avoiding the pipeline walk on all
calls but the first one, and drop the media_entity stream_count field.
media_pipeline_stop() is updated accordingly.

media: v4l2-core: Initialize h264 scaling matrix
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.

media: imx: imx-mipi-csis: Add output format
Due to how pixel components are transmitted on the CSI-2 serial bus
and how they are deserialized by the CSI-2 receiver, the component
ordering might change and the image formats on the sink and source pads
of the receiver should reflect it.
For RGB24, in example, the component ordering on the wire as described by
the CSI-2 specification matches the BGR888 format, while once
deserialized by the CSIS receiver it matches the RGB888 format.
Add an additional .output field to struct csis_pix_format to allow
propagating the correct format to the source pad after a format
configuration on the sink.
The change is only relevant for RGB24 but paves the way for further
format translations in future.

Add support for the BGR888_1X24 image format.
No existing media bus codes describe exactly the way data is transferred
on the CSI-2 bus. This is not a new issue, the CSI-2 YUV422 8-bit format
is described by MEDIA_BUS_FMT_UYVY8_1X16 which is an arbitrary
convention and not an exact match. Use the MEDIA_BUS_FMT_BGR888_1X24 to
follow the same convention, based on the order in which bits are
transmitted over the CSI-2 bus.

The CSI bridge should operate in dual components mode when it is
connected to a pixel transmitter that transfers two components at a time
in YUV 422 formats (16 bits, Y + U/V).
Use the image format variants to determine if single or dual component mode
should be used.
Add a note to the TODO file to record that the list of supported formats
should be restricted to the SoC model the CSI bridge is integrated on
to avoid potential pipeline mis-configurations.
