From 76db93d03f1e9a9a3371f787ae30780cdf10400c Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Sun, 19 Nov 2006 19:45:26 -0300 Subject: V4L/DVB (4846): Create new lgh06xf atsc tuner module 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 Signed-off-by: Michael Krufky Signed-off-by: Mauro Carvalho Chehab --- drivers/media/dvb/b2c2/Kconfig | 1 + drivers/media/dvb/b2c2/flexcop-fe-tuner.c | 10 +-- drivers/media/dvb/bt8xx/Kconfig | 2 +- drivers/media/dvb/bt8xx/dvb-bt8xx.c | 9 +- drivers/media/dvb/bt8xx/dvb-bt8xx.h | 2 +- drivers/media/dvb/dvb-usb/Kconfig | 1 + drivers/media/dvb/dvb-usb/cxusb.c | 11 +-- drivers/media/dvb/frontends/Kconfig | 8 ++ drivers/media/dvb/frontends/Makefile | 1 + drivers/media/dvb/frontends/lg_h06xf.h | 64 -------------- drivers/media/dvb/frontends/lgh06xf.c | 139 ++++++++++++++++++++++++++++++ drivers/media/dvb/frontends/lgh06xf.h | 35 ++++++++ 12 files changed, 192 insertions(+), 91 deletions(-) delete mode 100644 drivers/media/dvb/frontends/lg_h06xf.h create mode 100644 drivers/media/dvb/frontends/lgh06xf.c create mode 100644 drivers/media/dvb/frontends/lgh06xf.h (limited to 'drivers/media/dvb') diff --git a/drivers/media/dvb/b2c2/Kconfig b/drivers/media/dvb/b2c2/Kconfig index a0dcd59da76..79875958930 100644 --- a/drivers/media/dvb/b2c2/Kconfig +++ b/drivers/media/dvb/b2c2/Kconfig @@ -9,6 +9,7 @@ config DVB_B2C2_FLEXCOP select DVB_STV0297 if !DVB_FE_CUSTOMISE select DVB_BCM3510 if !DVB_FE_CUSTOMISE select DVB_LGDT330X if !DVB_FE_CUSTOMISE + select DVB_TUNER_LGH06XF if !DVB_FE_CUSTOMISE help Support for the digital TV receiver chip made by B2C2 Inc. included in Technisats PCI cards and USB boxes. diff --git a/drivers/media/dvb/b2c2/flexcop-fe-tuner.c b/drivers/media/dvb/b2c2/flexcop-fe-tuner.c index b8ba8786345..c2b35e36624 100644 --- a/drivers/media/dvb/b2c2/flexcop-fe-tuner.c +++ b/drivers/media/dvb/b2c2/flexcop-fe-tuner.c @@ -14,7 +14,7 @@ #include "stv0297.h" #include "mt312.h" #include "lgdt330x.h" -#include "lg_h06xf.h" +#include "lgh06xf.h" #include "dvb-pll.h" /* lnb control */ @@ -303,12 +303,6 @@ static int flexcop_fe_request_firmware(struct dvb_frontend* fe, const struct fir return request_firmware(fw, name, fc->dev);
