2013-01-24[media] stv090x: On STV0903 do not set registers of the second pathAndreas Regel
Sometimes there is a problem when trying to access the non-existing registers of the second demodulator path on the STV0903. This change removes the calls in case the driver is used on a STV0903.

2013-01-24[media] mb86a20s: remove global BER/PER counters if per-layer counters vanishMauro Carvalho Chehab
If, for any reason, all per-layers counters stop, remove the corresponding global counter. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-01-24[media] mb86a20s: add a logic for post-BER measurementMauro Carvalho Chehab
The logic here is similar to the preBER. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-01-24[media] mb86a20s: fix the PER reset logicMauro Carvalho Chehab
The logic that resets the device is wrong. It should be resetting just the layer that got read. Also, stop is needed before updating the counters. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-01-24[media] mb86a20s: some fixes at preBER logicMauro Carvalho Chehab
The logic that resets the device is wrong. It should be resetting just the layer that got read. Also, stop is needed before updating the counters. While there, rename it, as we'll soon introduce a postBER logic there. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-01-24[media] mb86a20s: add block count measures (PER/UCB)Mauro Carvalho Chehab

2013-01-23[media] mb86a20s: add CNR measurementMauro Carvalho Chehab
Add Signal/Noise ratio measurement. On this device, a global measure is taken by the demod. It also provides per-layer CNR measurements, based on Modulation Error measures (MER). Reviewed-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-01-23[media] mb86a20s: improve bit error count for BERMauro Carvalho Chehab
Do a better job on setting the bit error counters, in order to have all layer measures to happen in a little less than one second. Reviewed-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-01-23[media] mb86a20s: add BER measurementMauro Carvalho Chehab
Add the methods to read bit error/bit count measurements from mb86a20s. On ISDB-T devices, those reads are done per layer. However, as userspace applications may not be aware of that, add a global measure that will sum the bit errors and bit counts for each layer, storing them into a global value.

2013-01-23[media] mb86a20s: calculate statistics at .read_status()Mauro Carvalho Chehab
Instead of providing separate callbacks to read the several FE stats properties, the better seems to use just one method that will: - Read lock status; - Read signal strength; - if locked, get TMCC data; - if locked, get DVB statistics. As the DVB frontend thread will call this read_status callback on every 3 seconds, and userspace can even call it earlier, all stats data and layers layout will be updated together if available, with is a good thing.

2013-01-22[media] mb86a20s: improve error handling at get_frontendMauro Carvalho Chehab
The read/write errors are not handled well on get_frontend. Fix it, by letting the frontend cached values to represent the DVB properties that were successfully retrieved.

Tested by compilation only.
