This patch series is the result of some additional tests with the media
controller and
several different pure digital TV devices, using the dvb-usb, dvb-usb-v2 core
and
the siano driver.
It addresses some minor issues, and improves the graph representation of
those devices. In particular, the DVB USB v2 mxl111sf driver supports one
device that has:
- one tuner, provided by the MXL chipset;
- three demodulators (one for ATSC, one for ClearQAM and one for DVB-T), each
one using a different chip and different driver (lg2161, lgdt3305 and an
internal
DVB-T demodulator inside the MXL chipset);
- one demod, provided by the MXL chipset.
The graph for such design is at:

with is generated, after this changeset, using mc-nextgen-test tool, available
at:
https://git.linuxtv.org/mchehab/experimental-v4l-utils.git/log/?h=mc-next-gen-v2
The .dot file produced by the tool is at:

Before this patch series, the RF connector and tuner were not shown.
Also, the graph were missing the connections for the frontends 0 and 1.
