Probe for additional tvaudio devices, and allow tvaudio+tda7432 to co-exist. My STB TV PCI FM bttv card has a tda7432, a tda9850 and a tea6420 and with this patch it finally works again (probably for the first time in many years). Signed-off-by:

Note that the private chroma agc control has been replaced with the standard CHROMA_AGC control. Also fixes a mute/automute problem where closing the file handle would force mute on. That's not what you want since that would make the mute state out of sync with the mute control. Instead check against the user count. Signed-off-by:

- don't return -EINVAL for invalid field types, handle those as if it was FIELD_ANY. - the handling of FIELD_SEQ_BT/TB was wrong as well: if such field formats aren't supported, then fall back to FIELD_ANY instead of returning an error. Signed-off-by:

If no tuner is present, then disable the tuner and frequency ioctls. We can remove a number of checks from those ioctls testing for the presence of a tuner. Also remove some tuner type checks (now done by the core) and fix an error return when the prio check fails. Finally some 'unlikely' statements are removed since those only make sense in tightly often executed loops, otherwise they just clutter up the code. Signed-off-by:

VIDIOC_DBG_G_CHIP_IDENT is a prerequisite for the G/S_REGISTER ioctls. In addition, add support to call G/S_REGISTER for supporting i2c devices. Signed-off-by:

This driver now passes the tuner and frequency tests of v4l2-compliance. It's the usual bugs: frequency wasn't clamped to the valid frequency range, incorrect tuner capabilities and tuner fields not filled in, missing test for invalid tuner index, no initial frequency and incorrect error handling.

Putting em28xx in suspend mode when a feed stops is just plain wrong. Every time a new PES filter is changed, the DVB demux code will stop the current feed, and then start a new one. If are there any code that switches off the frontend, via some GPIO setting, this would make the DVB fail. This condition was actually trigged with one device, during DVB scan, as, during scan, it is common that userspace apps to change the filter several times, in order to get all tables. Also, this is not needed at all, since the em28xx code already hooks into ops.ts_bus_ctrl(). This warrants that em28xx can check there if DVB frontend is in usage or not. The code there already puts the device on suspend mode, if the DVB frontend is not used (closed). Signed-off-by: -

Instead of using 3.3 MHz IF, use 4MHz. That's the standard value for the demod, and, while it can be adjusted, 3.3 MHz is out of the recommended range. So, let's stick with the default. With regards to the IF voltage level, instead of using 0.5 V(p-p) for IF, use 2V, giving a 12dB gain. The rationale is that, on PixelView SBTVD Hybrid, even 2V(p-p) would be in the nominal range for IF, as the maximum range on this particular device is 3V. A higher gain here should help to improve reception under weak signals. Signed-off-by: -
