Use TUNER_SET_CONFIG to set configuration in tda9887's private state structure, rather than storing tda9887-specific configuration within struct tuner. Update handling of TUNER_SET_CONFIG by tuner-core, to call &t->fe.ops.analog_demod_ops rather than &t->fe.ops.tuner_ops analog_demod_ops.set_config passes the request to tuner_ops.set_config, so this does not break other drivers.

The auto selection of pertinent helper chips (VIDEO_HELPER_CHIPS_AUTO) should select the wm8775 driver, which is used by at least one Conexant 2388x based card (Hauppauge HVR-1300), if VIDEO_CX88 is selected. Signed-off-by:

All cx2388 boards need the line-in audio to be routed from an external ADC (refered to as "ADC mode" in the spec sheet), since the chip is uncapable of dealing with baseband audio directly. So... this patch enables normal mode when using the tuner (TV or Radio), and enables ADC mode with any other source. It'll probably only work with boards that have supported ADCs (such as the Wolfson wm9775) Signed-off-by:

We should not mute the audio input when we stop the codec, because it will interfere with the live uncompressed stream. Signed-off-by:

Fix lack of audio on the MPEG-2 stream of wm8775 based blackbirds. The wm8775 module initializes the audio input at "route 2", which doesn't hold true for all boards. The HVR-1300, for example, uses route 1 for tuner audio, and route 2 for baseband. So we must route the audio to the proper input depending on what video input is being used. Signed-off-by:

Remove the unnecessary BLACKBIRD_UNMUTE calls to the mpeg encoder in cx88-blackbird.c The encoder is never muted, hence unmuting should then only be necessary once after hardware initialization. I tested this from warm boots and cold boots (with long power down time to ensure the sram in the chip is emptied), and found that after the firmware upload the encoder is apparently not muted, making the unmutes unnecessary.

This patch should fix the 'muted audio' and 'raspy audio' problem for mpeg2 streams out of cx88-blackbird devices. Especially mythtv users would find that the audio would often sound bad (aliased, or 'raspy'), mainly related to channel changes, many (all?) other users would find that there was no audio at all in the mpeg data from the encoder chip, unless the audio was manually unmuted. The patch includes the following modifications: Don't actually start the mpeg2 encoder until the device is read from by the application. Wait until the audio is stable for at least 400ms before starting the mpeg encoder. Mute/Unmute the audio when starting/stopping the mpeg encoder. Stop the mpeg encoder when changing parameters and when changing tuner frequency. Add a variable 'mpeg_active' to struct cx8802_dev to allow tracking of whether or not the mpeg2 encoder is active. Load the firmware on cx88-blackbird driver load. Signed-off-by:

On the s5h1409 demod, the IF frequency for VSB is limited to 44 / 5.38 MHz. Hardcode VSB IF frequency within the driver to 44 / 5.38 MHz. QAM IF frequency remains configurable via attach-time configuration. Acked-by:

If we pass TDA18271_GATE_DIGITAL into tda18271_attach(), it will always try to use the digital demodulator's i2c gate. If we pass TDA18271_GATE_ANALOG into tda18271_attach(), it will always try to use the analog demodulator's i2c gate. If we pass TDA18271_GATE_AUTO into tda18271_attach(), it will try to use the analog demodulator's i2c gate when tuning in analog mode, and it will try to use the digital demodulator's i2c gate when tuning in digital mode.

saa7134 were converted to video_ioctl2, but saa7134_empress weren't. This broke saa7134-empress, since it were dependent of saa7134_common_ioctl.
