Previously the pvrusb2 driver just started with the default input to
be "television".  But if the device doesn't support an analog tuner
then this default must be different.  New logic here selects a
reasonable default based on the actual valid set of available inputs.

When an enumeration control is changed, the pvrusb2 driver assumed
that the enumeration values were continuous.  That is no longer true;
this change allows for properly input validation even when not all
enumeration values are legal (which can happen with input selection
based on what the hardware supports).

Now that the pvrusb2 driver can dynamically choose which inputs to
make available depending on the hardware, the enumeration of input
choices is no longer a contiguous range of integers.  Unfortunately
this causes a problem in the v4l2 implementation since the input
enumeration requires continuity in the API.  This change implements a
mapping in order to preserve the v4l2 interface requirement.

This follows from defining the available inputs as device attributes.
This change causes the driver to adjust its list of inputs based on
those attributes.  Now, for example, the FM radio will appear as a
choice only if the hardware supports an FM radio.

Different devices support different input types.  Up until now we've
really been assuming that everyone has an analog tuner, an FM radio,
composite, and s-video inputs.  But as we add other devices, these
assumptions are no longer true.  The way to deal with this is to
define the available inputs as additional device attributes, so that
the driver can adjust its internal behavior accordingly.

The PixelView PlayTV card definition structure was missing initialization of
the tuner_addr and radio_addr fields. As a result it was impossible to have the
tuner initialized using parameters specified while loading the bttv.ko module.

This regression became visible after the v4l rearrangements introduced
somewhere around 2.6.15 kernel version.

The root cause for the tuner initialization failure is located in the
attach_inform function in the bttv-i2c.c file.

There at the very beginning the addr variable holding the tuner device address
is initialized with the value taken from the bttv_tvcards array.

For the PixelView PlayTV card the tuner address field (and the radio address as
well) was uninitialized, and thus equal 0. Later in that function execution of
the TUNER_SET_TYPE_ADDR tuner command is guarded with check for the tuner
address either equal ADDR_UNSET, or client->addr.

Since both are non-zero (the latter in case of the card owned by me at the
runtime is equal 0x61) the TUNER_SET_TYPE_ADDR command is not executed, and
consequently in the tuner_attach function in the tuner-core.c file call to
i2c_attach_client does not result in assigning the tuner type variable with the
requested value.

Providing initialization of the tuner_addr and radio_addr with ADDR_UNSET
values as it is already done for other tv cards defined in bttv-cards.c ensures
that the tuner initialization is done correctly, just as it used to be in the
2.6.14 kernel.

Currently (in linux-2.6.24, but linux-dvb hg looks similar), the
dmx_output_t in the dmx_pes_filter_params decides two things: whether
output is sent to demux0 or dvr0 (in dmxdev.c:dvb_dmxdev_ts_callback),
*and* whether to depacketise TS (in dmxdev.c:dvb_dmxdev_filter_start).
As it stands, those two things can't be set independently: output
destined for demux0 is depacketised, output for dvr0 isn't.

This is what you want for capturing multiple audio streams from the same
multiplex simultaneously: open demux0 several times and send
depacketised output there. And capturing a single video stream is fine
not what you want: you want multi-open (so demux0, not dvr0), but you
want the TS nature preserved (because that's what you want on output, as
you're going to re-multiplex it with the audio).

At least one existing solution -- GStreamer -- sends all its streams
simultaneously via dvr0 and demuxes again in userland, but it seems a
bit of a shame to pick out all the PIDs in kernel, stick them back
together in kernel, and send them to userland only to get unpicked
again, when the alternative is such a small API addition.

The attached patch adds a new value for dmx_output_t:
DMX_OUT_TSDEMUX_TAP, which sends TS to the demux0 device. With this
patch and a dvb-usb-dib0700 (and UK Freeview from Sandy Heath), I can
successfully capture an audio/video PID pair into a TS file that mplayer
can play back.

Only attach cameras to the host interface for probing, then detach until
open. This allows platforms with several cameras on an interface,
physically supporting only one camera, to handle multiple cameras and
activate them selectively after initial probing. The first attach during
probe is needed to activate the host interface to be able to physically
communicate with cameras.

This patch adds support for the following saa7134 xc3028 based boards:

133 -> AVerMedia Hybrid TV/Radio (A16D)         [1461:f936]
134 -> Avermedia M115                           [1461:a836]
135 -> Compro VideoMate T750                    [185b:c900]

This is based on a original patch thanks to Markus Rechberger that added xc3028
gpio init code for the above boards.

This patch moves saa7134_tuner_callback to saa7134-cards, originally used only
by tda8290 DVB-S boards. The callback was made more generic to support other
tuners.

Currently, it supports both tda8290 and xc2028/xc3028 tuners. Added also the
basis for xc5000 tuner callback.
