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:

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: -

Always init the frontend when set_frontend is called. The rationale is: it was noticed that, on some devices, it fails to lock with a different channel. It seems that some other registers need to be restored to its initial state, when the channel changes. As it is better to reset everything, even wasting a few more miliseconds than to loose channel lock, let's change the logic to always reset. Signed-off-by: -

Use the AGC settings present on a newer device. The initial settings were taken from one of the first devices with mb86a20s, and there are several reports that this is not working properly on some places. So, instead of keeping using it, get the parameters taken from a newer device. Tests are welcomed. Tested also with cx231xx PixelView SBTVD Hybrid with no regressions noticed so far. Signed-off-by: -

State 9 means TS started to be output, and it should be associated with FE_HAS_SYNC. The mb86a20scan get CNR statistics at state 7, when frame sync is obtained. As CNR may help to adjust the antenna, provide it earlier. A latter patch could eventually start outputing MER measures earlier, but that would require a bigger change, and probably won't be better than the current way, as the time between changing from state 8 to 9 is generally lower than the time to get the stats collected.

The new eeproms with 16 address width still have the the device config dataset (the content of the old 8 bit eeproms) embedded. Hauppauge also continues to include the tveeprom data structure inside this dataset in their devices. The start address of the dataset depends on the start address of the microcode and a variable additional offset. It should be mentioned that Camera devices seem to use a different dataset type, which is not yet supported. Tested with devices "Hauppauge HVR-930C". I've also checked the USB-log from the "MSI Digivox ATSC" and it works the same way. Signed-off-by:

We currently reserve an array of 256 bytes for the eeprom content in the device struct. For eeproms with 16 bit address width it might even be necessary to increase the buffer size further. Having such a big chunk of memory reserved even if the device has no eeprom and keeping it after it has already been processed seems to be a waste of memory. Change the code to allocate + free the eeprom memory dynamically. This also makes it possible to handle different dataset sizes depending on what is stored/found in the eeprom. Signed-off-by:
