2006-12-10V4L/DVB (4890): Lgdt330x: fix signal / lock status detection bugMichael Krufky
In some cases when using VSB, the AGC status register has been known to falsely report "no signal" when in fact there is a carrier lock. The datasheet labels these status flags as QAM only, yet the lgdt330x module is using these flags for both QAM and VSB. This patch allows for the carrier recovery lock status register to be tested, even if the agc signal status register falsely reports no signal. Thanks to jcrews from #linuxtv in irc, for initially reporting this bug. Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-12-10V4L/DVB (4869): Lgh06xf: use return value of dvb_pll_configure()Michael Krufky
Use return value of dvb_pll_configure() to fill priv->frequency In lgh06xf_set_params: Rename int variable "err" to "result". Remove needless calculation of the set frequency, since this value is now being returned by dvb_pll_configure().

2006-12-10V4L/DVB (4868): Dvb-pll: return frequency set by dvb_pll_configure()Michael Krufky
This patch removes some duplicated code by returning the frequency set by dvb_pll_configure(), instead of recalculating it again in dvb_pll_set_params() and dvb_pll_calc_regs(). If the return value of dvb_pll_configure is less than zero, it is an error code. Otherwise, the return value is the frequency actually set by the function.

2006-12-10V4L/DVB (4846): Create new lgh06xf atsc tuner moduleMichael Krufky
This patch creates a new atsc tuner module for the LG TDVS-H06xF ATSC tuners, called lgh06xf. The purpose of this change is to reduce some duplicated code, and to allow the lgh06xf tuner code to take advantage of dvb_attach(). As a side effect, the dependency of dvb-bt8xx on dvb-pll has been removed, since the lgh06xf module itself will use dvb-pll, while remaining optional for the dvb-bt8xx driver through the use of DVB_FE_CUSTOMISE Acked-by: Andrew de Quincey <adq_dvb@lidskialf.net> Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2006-12-10V4L/DVB (4789): Lgdt330x: SNR and signal strength reportingTrent Piepho
Update the SNR calculations to use the new dvb_math log function, and add SNR calculations for all supported modulations for both lg dt3302 and dt3303. The QAM equations don't appear in the dt3302 datasheet, so the ones from the dt3303 datasheet were used. SNR returned is the actual value in dB as 8.8 fixed point. Reporting of real signal strength isn't supported, so rather than return 0, which confuses some software and users, a re-scaled SNR value is returned. Code originally by Rusty Scott.

2006-11-03V4L/DVB (4751): Fix DBV_FE_CUSTOMISE for card drivers compiled into kernelTrent Piepho
When a front-end is disabled, card drivers that use it are compiled with a stub version of the front-end's attach function. This way they have no references to the front-end's code and don't need it to be loaded. If a card driver is compiled into the kernel, and a front-end is a module, then that front-end is effectively disabled wrt the card driver. In this case, the card driver should get the stub version. This was not happening. The stub vs real attach function selection is changed so that when the front-end is a module the real attach function is only used if the card driver is a module as well. This means a module front-end will be supported by card drivers that are modules and not supported by card drivers compiled into the kernel.
