2012-03-20[media] stb0899: fix the limits for signal strength valuesKlaus Schmidinger1-3/+5
stb0899: fix the limits for signal strength values stb0899_read_signal_strength() adds an offset to the result of the table lookup. That offset must correspond to the lowest value in the lookup table, to make sure the result doesn't get below 0, which would mean a "very high" value since the parameter is unsigned. 'strength' and 'snr' need to be initialized to 0 to make sure they have a defined result in case there is no "internal->lock".

2012-03-20[media] m88rs2000 ver 1.13 Correct deseqc and tuner gain functionsMalcolm Priestley1-9/+8
Remove incorrect SEC_MINI_B settings-TODO complete this section. Correct break and remove return -EINVAL within set tone. It appears there is a bug that occasionally something other than ON/OFF is sent stalling the driver. Just continue and write back registers. Set register b2 in setup. This is the set voltage pin which isn't used in lmedm04 driver but it is always set to 0x1. Correct the if statements in set_tuner_rf.

2012-03-20[media] au8522: bug-fix: enable modulation AFTER tune (instead of before tuning)Michael Krufky1-5/+5
The au8522 driver programs the tuner after programming the demodulator, but the tuner should be programmed first. This patch fixes this behavior. EDIT: Apparantly Devin created a similar patch some time ago, but hasn't submitted it for merge. I never saw his patch, but I thank him anyhow for his efforts. In addition, Devin pointed out a flaw in my patch: This newly generated patch takes Devin's comments into account.

2012-03-19[media] m88rs2000 1.12 v2 DVB-S frontend and tuner moduleMalcolm Priestley4-0/+981
Support for m88rs2000 chip used in lmedm04 driver. Note there are still lock problems. Slow channel change due to the large block of registers sent in set_frontend. Version 2 differences. Front end is completely shut down when in sleep mode. This allow user to regain control of device. Kaffeine scan problem solved by removing register calls from get_frontend. Kaffeine seems to call get_frontend when updating signal data. This can happen in the middle of a tune stalling the driver. Change calculations to those in the DS3000 driver.

2012-03-19[media] STV0288 increase delay between carrier searchMalcolm Priestley1-1/+1
The current delay of 30uS is too short to recover any carrier. In the lmedm04 driver delays were added to overcome carrier lock problems. The typical delay was 30mS (2 x 15ms register write 0x2c and read 0x24). Other drivers that use STV0288 don't appear to have any delay are likely to have also suffered this problem.

2012-03-08[media] cx22702: Fix signal strengthJean Delvare1-3/+19
The signal strength value returned is not quite correct, it decreases when I increase the gain of my antenna, and vice versa. It also doesn't span over the whole 0x0000-0xffff range. Compute a value which at least increases when signal strength increases, and spans the whole allowed range. In practice I get 67% with my antenna fully amplified and 51% with no amplification. This is close enough to what I get on my other DVB-T adapter with the same antenna.

2012-01-21[media] drxk: Don't assume a default firmware nameMauro Carvalho Chehab1-3/+1
Move the ngene/ddbridge firmware into their drivers. There are two reasons for that: 1) The firmware used there didn't work for a few devices I tested here (Terratec H5, H6 and H7); 2) At least Terratec H7 doesn't seem to require a firmware for it to work. After this change, if firmware is not specified, the driver will use a rom-based firmware (this seems to be the case for Terratec H7, although I need to better check the USB dumps to be sure about that). In any case, the firmware seems to be optional, as the DRX-K driver don't return the firmware load error. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-01-11mb86a20s: Add a few more register settings at the init seqMauro Carvalho Chehab1-4/+12
Some time ago, Manoel sent us a patch adding more stuff to the init sequence. However, his patch were also doing non-related stuff, by changing the init logic without any good reason. So, it was asked for him to submit a patch with just the data that has changed, in order to allow us to better analyze it. As he didn't what it was requested, I finally found some time to dig into his init sequence and add it here. Basically, new stuff is added there. There are a few changes: 1) The removal of the extra (duplicated) logic that puts the chip into the serial mode; 2) Some Viterbi VBER measurement init data was changed from 0x00 to 0xff for layer A, to match what was done for layers B and C. None of those caused any regressions and both make sense on my eyes. The other parameters additions actually increased the tuning quality for some channels. Yet, some channels that were previously discovered with scan disappered, while others appeared instead. This were tested in Brasilia, with an external antena. At the overall, it is now a little better. So, better to add these, and then try to figure out a configuration that would get even better scanning results.
