The old cards.rst file doesn't exist anymore. Also, it is not
the right reference there, as it should be pointing to the
bttv-specific cardlist.

While test drivers is probably something that normal users
won't bother, it doesn't hurt to add them to the card list.
This way, all drivers, except for the ones under staging,
would be listed there.

The SPI cards are also under the concept of "platform" drivers
as defined at the section introduction.
So, add a SPI card list there.

Having a table with a list of all USB drivers seems worth,

The DVB cards.rst file is old and outdated. It also contains

There are several other USB cards. Most of them support just

The cardlist section is important for some boards, because they

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.
