* [media] mn88472: fix chip id check on probeAntti Palosaari2016-12-011-12/+12
| | | | | | | | | | | | | A register used to identify chip during probe was overwritten during firmware download and due to that later probe's for warm chip were failing. Detect chip from the another register, which is located on different register bank 2.

* [media] dvb: remove unused systime() functionArnd Bergmann2016-11-232-12/+0
| | | | | | | | | | The systime function uses struct timespec, which we want to stop using in the kernel because it overflows in 2038. Fortunately, this use in dibx000_common is in a function that is never called, so we can just remove it.

* [media] stv090x: use lookup tables for carrier/noise ratioJoerg Riechardt2016-11-231-6/+10
| | | | | | | | | | | | | | | | | | | The stv090x driver uses the lookup table for signal strength already, with this patch we use the lookup tables for carrier/noise ratio as well. This has the advantage, that values for DVB-S and DVB-S2 are now corresponding, while before they were way off. The values are now proportional to real carrier/noise ratio, while before they were corresponding to register values. So now applications are able to give the user real carrier/noise ratio. Because the output has to be within 0x0000...0xFFFF the three negative values for DVB-S2 are omitted. This is no significant loss, because reception is lost at 7.5 dB already (TT S2-1600, Cine S2), so the negative values are not really important, and also for DVB-S they don´t exist.

* [media] mn88473: refactor and fix statisticsAntti Palosaari2016-11-222-400/+161
| | | | | | | | | | | | | | | | | | | | | Remove DVB-T2 BER as it does not work at all and I didn't find how to fix. Fix DVB-T and DVB-C BER. It seems to return new some realistic looking values. Use (1 << 24) base for CNR calculations to keep it in line with dvb logarithm functions. Move all statistic logic to mn88473_read_status() function. Use regmap_bulk_read() for reading multiple registers as a one go. Many more and less minor changes.

* Revert "[media] dvb_frontend: merge duplicate dvb_tuner_ops.release ↵Mauro Carvalho Chehab2016-11-1815-16/+122

This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines.

* | [media] si2165: avoid division by zeroMatthias Schwarzott2016-09-221-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When si2165_init fails, the clk values in state are still at zero. But the dvb-core ignores the return value of init will call tune afterwards. This will trigger a division by zero when tuning. At least check for the variables to be non-zero before dividing. This happened for a system with WinTV HVR-4400 PCIe-card after suspend-to-disk. Do suspend-to-disk without accessing the DVB device before. After wakeup try to tune. si2165_init fails at checking the chip_mode and aborts. Then si2165_set_if_freq_shift will fail with div-by-zero.
