A new em28xx card was added upstream. Update cards list
accordingly.

It is interesting to have a card list also for cx231xx
driver, as it currently supports 27 different boards.

Improve the documentation by providing examples on how to test camera
capture on imx6q-sabresd via v4l2-ctl and Gstreamer.

In order to improve the documentation, provide the OV5640 MIPI module
part number that is used on the imx6q-sabresd board.

The current example for imx6q-sabresd is for a direct conversion pipeline.
Provide an extra example using unprocessed video capture for completeness.

The current instructions for imx6q-sabresd do not lead to functional
capture on OV5640 MIPI CSI-2.
The reason for this, as explained by Steve Longerbeam, is that OV5640 by
default transmits on virtual channel 0, not channel 1 as is given in the
instructions.
Adapt the instructions to use virtual channel 0 so that a working
camera setup can be achieved on imx6q-sabresd.
Also, since we are using an IC direct conversion pipeline, improve
the example by demonstrating colorspace and scaling.

The copyright info is not the most valuable information
there. Move them to the end.
While here, change the copyright to cover up to this

This file is very old, and doesn't match the current udev
behavior.
I wanted to preserve it, because we'll need some udev
description some day about how to keep names unique,
but there's nothing here to help with that...
So, be it: let's just discard this document, as it doesn't
provide anything useful anymore.

There aren't much to be done here... almost everything is
still valid. The supported boards even reflect the current
driver's state. Yet, some things changed, so let's keep
this document updated.

There are several things here that are outdated, because this
document was written a long time ago.
Update them to reflect the current status of the driver and
the media subsystem.

Do some cleanups at the document in order to mark two
literal blocks as such.
While here, simplify two block markups, using the less
verbose option (::).

There aren't many boards supported by this driver. So, add

This document is... old. The bttv driver was one of the first
drivers at the Kernel. So, the document became a little obsoleted.
Update it to reflect some changes that happened along the time
affecting this driver and the subsystem.

This document is very outdated, and doesn't match the
upstream current way.
Update it, making some parts a little bit more generic.
While the main focus of this document is digital TV
cards, its content also may also help someone with just
analog TV support.

While this is old, now that we moved the intro part of it,
its contents seem to be valid, if we mention that we're
talking only about the BT878 support.
Update the document title accordingly and remove the obsolete

Part of this document has nothing to do with the Avermedia

For ipu3 ImgU image processing, the frame data from TNR can feed into
DDR by Output Formatting System or feed into YUV downscaler to do YUV
downscaling for secondary output, which is usually used for display.
current ImgU image pipeline diagram misses the YUV downscaling,
this patch add it to aligh with actual hardware blocks.

Add the media graph topologies for the i.MX6Q SabreSD and SabreAuto.
This makes it easier to understand the topology and follow the
entity descriptions in the following sections.
Also clarify that the SabreSD and SabreLite media pipeline config examples
are for the i.MX6Q boards.

Most of the driver-specific documentation is meant to help
users of the media subsystem.
Move them to the admin-guide.
It should be noticed, however, that several of those files
are outdated and will require further work in order to make
them useful again.
