* [media] common: move media/common/tuners to media/tunersMauro Carvalho Chehab2012-08-13
| | | | | | | Move the tuners one level up, as the "common" directory will be used by drivers that are shared between more than one driver. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* [media] xc4000: add support for signal strength measuresMiroslav Slugen2012-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* [media] dvb: don't use DVBv3 bandwidth macrosMauro Carvalho Chehab2011-12-31
| | | | | | | Every frontend now uses DVBv5 way. So, let's not use the DVBv3 macros internally anymore. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] tuners: remove dvb_frontend_parameters from set_params()Mauro Carvalho Chehab2011-12-31
| | | | | | | | | | | This is a big patch, yet trivial: now that all tuners use the DVBv5 way to pass parameters (e. g. via fe->dtv_property_cache), the extra parameter can be removed from set_params() call. After this change, very few DVBv3 specific stuff are left at the tuners. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] xc4000: use DVBv5 parameters on set_params()Mauro Carvalho Chehab2011-12-31
| | | | | | | Instead of using DVBv3 parameters, rely on DVBv5 parameters to set the tuner. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] xc4000: Use kcalloc instead of kzalloc to allocate arrayThomas Meyer2011-12-30
| | | | | | | | | | | | The advantage of kcalloc is, that will prevent integer overflows which could result from the multiplication of number of elements and size and it is also a bit nicer to read. The semantic patch that makes this change is available in https://lkml.org/lkml/2011/11/25/107 Signed-off-by: Thomas Meyer <thomas@m3y3r.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* [media] xc4000: detect also xc4100Istvan Varga2011-07-27
| | | | | | | | | | Added code to detect the XC4100 chip, which is presumably an analog-only "value" version of the XC4000. It is not sure, however, if any devices using this have actually been produced and sold, so the patch may be unneeded.

* [media] xc4000: removed redundant tuner resetIstvan Varga2011-07-27
| | | | | | | | | | This patch causes the tuner reset command to be ignored in the firmware code, since this only happens when the BASE/INIT1 firmware is loaded by check_firmware(), and in that case check_firmware() already calls the reset callback before starting to load the firmware.

| | | | | | | | | | This patch implements setting the registers in xc4000_set_params() and xc4000_set_analog_params(). A new register is defined which enables filtering of the composite video output (this is needed to avoid bad picture quality with some boards).

| | | | | | | | | | | The following patch implements the xc4000_sleep() function.

| | | | | | | | | | | | This patch makes the following changes to the standards table: - added 'u16 int_freq' to struct XC_TV_STANDARD (needed for analog TV and radio, 0 for DVB-T) - added new standard for SECAM-D/K video with PAL-D/K audio - the 'int_freq' values are now specified in the table - changed VideoMode for NTSC and PAL-B/G standards Signed-off-by: Istvan Varga <istvan_v@mailbox.hu> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* [media] xc4000: handle dib0700 broken i2c stretchingDevin Heitmueller2011-07-27
| | | | | | | | | It was confirmed by DibCom that i2c stretching is broken in the i2c master on the dib7700. So we need to put a hack into the xc4000 driver to not complain in certain very specific cases where we know i2c stretching occurs.

* [media] xc4000: continued cleanup of the firmware loading routineDevin Heitmueller2011-07-27
| | | | | | | | | | Properly setup the standard firmware loading and scode loading, as well as getting rid of a ton of dead code.

* [media] xc4000: add code to do standard and scode firmware loadingDevin Heitmueller2011-07-27
| | | | | | | | | Add code to handle firmware blobs for the standard and scode. Note there appears to be some issue with loading the DTV8 standard firmware, probably related to direct/indirect mode.

* [media] xc4000: remove xc5000 firmware loading routineDevin Heitmueller2011-07-27
| | | | | | | | | Since we use the xc3028 version of the firmware file parsing routine (which includes support for scodes and separate blobs), we can drop the xc5000 version of the code.

* [media] xc4000: remove XREG_BUSY code only supported in xc5000Devin Heitmueller2011-07-27
| | | | | | | | | The xc4000 driver is based on the original xc5000 driver, and while the xc5000 supports the XREG_BUSY register, the xc4000 does not. So remove the code in question.

* [media] xc4000: cut over to using xc5000 version for loading i2c sequencesDevin Heitmueller2011-07-27
| | | | | | | | | | | | | The xc3028 version does i2c splitting in a different manner than xc4000 and xc5000, so reuse the xc5000 version of the routine (the key here being that xc4000 expects the first *two* bytes to be the same for splitting transactions. Doing it the xc3028 way was resulting in i2c errors partially through the firmware load. With this change, it would appear that the entire base firmware is being loaded successfully (product id now properly shows 0x0FA0).

* [media] xc4000: pull in firmware management code from xc3028Devin Heitmueller2011-07-27
| | | | | | | | | | | Switch over to using the firmware management routines from the tuner-xc2028, since that has support for scodes, etc. This code still requires signficant cleanup, and at this point the base firmware does not load properly (i2c write errors about 300 bytes in).
