Most of this originates from Michael Krufky <mkrufky@linuxtv.org>; these changes move LED control into separate functions. This is the first step in new work to make LED control a device-specific attribute. Signed-off-by:

The encoder is not a part of the pipeline when in digital mode, so streaming is OK in this case even when the encoder's firmware is not loaded. Modify the driver core handling of this scenario to permit streaming. Signed-off-by:

This is a major pvrusb2 change. The driver core has an algorithm that is used to cleanly sequence the changes needed to enable / disable video streaming. The algorithm had originally been written for analog streaming, but when in digital mode the pipeline is considerably Signed-off-by: -

Unlike analog control, control of the digital side is not nearly as uniform among different devices. So we have to specify the correct digital control scheme as a new device attribute. Signed-off-by:

This code is actually part of a larger set from Mike Krufky <mkrufky@linuxtv.org>, to support ATSC streaming from within the pvrusb2 driver. More to come... Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

The v4l2 implementation in pvru2b2 must produce a sane answer when asked, when the input choice is set to dtv. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

This patch adds support for the following saa7134 xc3028 based boards: 132 -> AVerMedia Cardbus TV/Radio (E506R) [1461:f436] 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. Signed-off-by: -

Only tm6000 needs to be aware when a frequency is being changed. This seems to improve channel change detection. Other bridges don't need this. So, better to discard any errors if this fails, and proceed changing the channels. Signed-off-by: -

It seems that on this board, the demodulator provides the pullup on the I2C bus, which means that calling i2c_gate_ctrl crashes the bus. Turn this off and the xc3028 can talk OK. Also fix some GPIO related settings that became more clear through working on this. Some changes made by Mauro Chehab to allow merging it with some other xc3028 patches. Signed-off-by:
