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,

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

The DVB cards.rst file is old and outdated.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

As all USB cards already have their own card lists, just drop

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.
