* | [media] si2165: only write agc registers after reset before start_syncroMatthias Schwarzott2015-12-031-17/+15
| | | | | | | | | | | | | | | | Datasheet says they must be rewritten after reset. But it only makes sense to write them when trying to tune afterwards. Signed-off-by: Matthias Schwarzott <zzam@gentoo.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* | [media] stb6100: get rid of get_state()/set_state()Mauro Carvalho Chehab2015-11-173-72/+54
| | | | | | | | | | | | | | | | | | | | | | It is tricky to get rid of those ops here, as the stv0299 driver wants to set frequency in separate from setting the bandwidth. So, we use a small trick: we temporarely fill the cache with 0 for either frequency or bandwidth and add some logic at set_params to only change the property(ies) that aren't zero.

* | [media] tda6655: get rid of get_state()/set_state()Mauro Carvalho Chehab2015-11-171-36/+0
| | | | | | | | | | | | | | | | | | | | Those ops aren't used by any driver, with is weird. I suspect that mantis_vb3030 driver were not working properly... Anyway, now that the driver uses the set_parms, the DVB frontend core should do the right thing. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* | [media] tda8261: don't use set_state/get_state callbacksMauro Carvalho Chehab2015-11-172-99/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Those callbacks are meant to be used only on some very specific cases. There's absolutely no need to do that at tda8261, as the only parameter that it allows to be set/get is the frequency. So, use the standard get_params() and get_frequency() kABI ops. There's no need to touch at any bridge driver, as all interactions are done via the macros at tda8261_cfg.h. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* | [media] tda665x: split set_frequency from set_stateMauro Carvalho Chehab2015-11-171-76/+85
| | | | | | | | | | | | | | | | | | On tda665x, set_state only sets frequency. As the kABI for set_state is meant to be used only on special cases, split the function into two, in order to allow it to be latter used by a DVBv5 cache params logic.

* | [media] stb6100: get rid of tuner_state at struct stb6100_stateMauro Carvalho Chehab2015-11-172-6/+4
| | | | | | | | | | | | | | | | | | | | | | The stb6100 driver has a struct tuner_state on its state struct, that it is used only to store the bandwidth. Even so, this struct is not really used, as every time the bandwidth is get or set, it goes through the hardware. So, get rid of that. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* | [media] dvb_frontend.h: get rid of unused tuner params/statesMauro Carvalho Chehab2015-11-171-17/+6
|/ | | | | | | | | | | | | | | | | | | | There are several tuner_param values that aren't by any driver or core: DVBFE_TUNER_TUNERSTEP DVBFE_TUNER_IFFREQ DVBFE_TUNER_REFCLOCK DVBFE_TUNER_IQSENSE DVBFE_TUNER_DUMMY Several of those correspond to the values at the tuner_state struct with is also only initialized by not used anyware: u32 tunerstep; u32 ifreq; u32 refclock; It doesn't make sense to keep anything at the kABI that it is not used. So, get rid of them. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

As typically the b2120 reference design ships with a b2004a daughter board, which can accept two dvb NIM cards, and each b2100A NIM has 2x stv0367 demods and 2x NXPs tuner on it. In such circumstances it is useful to print the i2c address on error messages to know which one is failing due to I2C issues.

| * [media] dvb-frontends: Make all DVB Frontends visible if COMPILE_TEST=yGeert Uytterhoeven2015-08-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | Make the DVB Frontends menu visible when compile-testing, to allow selecting additional drivers on top of the drivers that are already automatically selected if MEDIA_SUBDRV_AUTOSELECT is enabled. Without this, many drivers stay disabled during e.g. allmodconfig. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

| | | | | | | | | | | | | | | | | | Implement DVBv5 CNR, signal strength, BER and block errors. Wrap legacy DVBv3 statistics to DVBv5 internally. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
| * [media] tda10071: do not get_frontend() when not readyAntti Palosaari2015-08-111-1/+1
| | | | | | | | | | | | | | | | | | This is a bit hack, but returning error when driver is not tuned yet causes DVBv5 zap stop polling DVBv5 statistics. Thus return 0 even callback is called during invalid device state. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
| * [media] tda10071: protect firmware command exec with mutexAntti Palosaari2015-08-112-3/+10
| | | | | | | | | | | | | | | | | | | | There should be clearly some lock in order to make sure firmware command in execution is not disturbed by another command. It has worked as callbacks are serialized somehow pretty well and command execution happens usually without any delays.

| | | | | | | | | | | | | | | | | | | | | | On power-on LNB power supply voltage is disabled, due to that no need to disable it during probe. Tone is supply is hard-coded as external tone coming from the demodulator. Program both voltage and tone on set_voltage(). Use register cache to prevent unneeded programming.
