2012-01-16[media] xc4000: add support for signal strength measuresMiroslav Slugen1-0/+86
In xc4000 chipsets real signal and noise level is stored in register 0x0A and 0x0B,so we can use those registers to monitor signal strength. I tested this patch on 2 different cards Leadtek DVR3200 and DTV2000H Plus, both with same results, I used special antenna hubs (toner 4x, 6x, 8x and 12x) with mesured signal lost, both registers are in dB value, first represent signal with limit value -113.5dB (should be -114dB) and exactly match with test results. Second represents noise level also in dB and there is no maximum value, but from tests we can drop everything above 32dB which tuner realy can't use, signal was usable till 20dB noise level. In digital mode we can take signal strength but sadly noise level is not relevant and real value is stored in demodulator for now just zl10353, also digital mode is just for testing, because it needs changing other parts of code which reads data only from demodulator. In analog mode I was able to test only FM radio, signal level is not important, it says something about cable and hub losts, but nothing about real quality of reception, so even if we have signal level at minimum 113dB we can still here radio, because of that it is displaied only in debug mode, but for real signal level is used noise register which is again very accurate, radio noise level was betwen 6-20dB for good signal, 20-25dB for medium signal, and above 25dB signal is unusable. For now real benefit of this patch is only for FM radio mode. Signed-off-by: Miroslav Slugen <thunder.mmm@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-01-06[media] xc3028: fix center frequency calculation for DTV78 firmwareGianluca Gennari1-10/+16
This patch replaces the previous one proposed in the thread "xc3028: force reload of DTV7 firmware in VHF band with Zarlink demodulator", at the linux-media@vger.kernel.org ML. The problem is that the firmware DTV78 works fine in UHF band (8 MHz bandwidth) but is not working at all in VHF band (7 MHz bandwidth). Reading the comments inside the code, I figured out that the real problem could be connected to the formula used to calculate the center frequency offset in VHF band. In fact, removing this adjustment fixes the problem: if ((priv->cur_fw.type & DTV78) && freq < 470000000) offset -= 500000; This is coherent to what was implemented for the DTV7 firmware by an Australian user: if (priv->cur_fw.type & DTV7) offset += 500000; In the end, now the center frequency is the same for all firmwares (DTV7, DTV8, DTV78) and doesn't depend on channel bandwidth. The final code looks clean and simple, and there is no need for any "magic" adjustment: if (priv->cur_fw.type & DTV6) offset = 1750000; else /* DTV7 or DTV8 or DTV78 */ offset = 2750000; Signed-off-by: Gianluca Gennari <gennarone@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-01-04[media] Don't test for ops->info.type inside driversMauro Carvalho Chehab1-1/+6
Now, ops->info.type is handled inside the dvb_frontend core, only for DVBv3 calls, and according with the delivery system. So, drivers should not care or use it, otherwise, it may have issues with DVBv5 calls. The drivers that were still using it were detected via this small temporary hack: --- a/include/linux/dvb/frontend.h +++ b/include/linux/dvb/frontend.h @@ -29,13 +29,16 @@ #include <linux/types.h> typedef enum fe_type { +#if defined(__DVB_CORE__) || !defined (__KERNEL__) FE_QPSK, FE_QAM, FE_OFDM, FE_ATSC +#else +FE_FOOO +#endif } fe_type_t; - typedef enum fe_caps { FE_IS_STUPID = 0, FE_CAN_INVERSION_AUTO = 0x1, Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-01-04[media] mt2063: Fix analog/digital set params logicMauro Carvalho Chehab2-201/+190
The driver were using a hacky way of setting analog and digital frequencies. Remove the hack and properly add the tuner logic for each supported type of standard. I was tempted to add more standards there, like SECAM and to fix radio (as stepping seems broken), but I opted to keep it as-is, as tests would be needed to add additional standards.
