2009-03-25tda827x: fix locking issues with DVB-CMauro Carvalho Chehab
From: klaas de waal <klaas.de.waal@gmail.com> Separate tuning table for DVB-C solves tuning problem at 388MHz TechnoTrend C-1501 DVB-C card does not lock on 388MHz. I assume that existing frequency table is valid for DVB-T. This is suggested by the name of the table: tda827xa_dvbt. Added a table for DVB-C with the name tda827xa_dvbc. Added runtime selection of the DVB-C table when the tuner is type FE_QAM. This should leave the behaviour of this driver with with DVB_T tuners unchanged. This modification is in file tda827x.c The tda827x.c gives the following warning message when debug=1: tda827x: tda827x_config not defined, cannot set LNA gain! Solved this by adding a tda827x_config struct in budget-ci.c. Priority: normal Signed-off-by: Klaas de Waal <klaas.de.waal@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-02-08tda827x: Be sure that gate will be open/closed at the proper timeMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@redhat.com> The gate control logic is broken: several routines just keep it open; other rotines close it properly; there are even other routines that assumes that it is open without really checking or opening it. Instead of having to manually handle the gate control and having such troubles, let a sub-routine take care of the gate, opening it before i2c_transfer and closing it after that. This avoids leaving the gate into a random state. Priority: normal CC: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-08tda827x: fix returned frequencyMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@redhat.com> Probably due to a removed code, tda827x were doing some wrong calculus at the returned frequency. I suspect that the original idea were to return the programmed divisor converted into frequency again. However, the current code is sometimes multiplying the programmed frequency by 62500, and, on other cases, like radio, it dividing it by 1000. Instead of doing such math, let's just store the frequency value as requested by the caller module. CC: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Move tuners to common/tuners There were several issues in the past, caused by the hybrid tuner design, since now, the same tuner can be used by drivers/media/dvb and drivers/media/video. This patch moves those common tuners into a common dir. It also moves saa7146 driver into drivers/media/video, where other hybrid drivers are placed. Kconfig items were rearranged, to split V4L/DVB core from their drivers. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
