From: Akihiro Tsukada <tskd2@xxxxxxxxxxx> This patch adds driver for 774 Friio White, ISDB-T USB receiver Friio White is an USB 2.0 ISDB-T receiver. (http://www.friio.com/) The device has a GL861 chip and a Comtech JDVBT90502 canned tuner module. This driver ignores all the frontend_parameters except frequency, as ISDB-T shares the same parameter configuration across the country and thus the device can work like an intelligent one. As this device does not include a CAM nor hardware descrambling feature, the driver passes through scrambled TS streams. There is Friio Black, a variant for ISDB-S, which shares the same USB Vendor/Product ID with White, but it is not supported in this driver. They should be identified in the initialization sequence, but this feature is not tested. Priority: normal Signed-off-by: Akihiro Tsukada <tskd2@xxxxxxxxxxx> --- Currently, all the Japanese Digital TV broadcasters, including the charge-free ones, scramble their programs except the tiny sized versions for cellular phones (called "1 seg." program). "BCAS" card is used to descramble those normal sized programs, and a private agency named "BS Conditional Systems" exclusively issues the cards only as a bundle for the approved receiver devices. Friio White is not, so it does not include a BCAS card. There are some descrambler software using a BCAS card from somewhere else with a PC/SC reader. Examples of these software include, filter command: http://www.marumo.ne.jp/junk/arib_std_b25-0.2.4.lzh Gstreamer plugin: http://2sen.dip.jp/cgi-bin/dtvup/source/up0158.zip But you have to note that their use may violate the card's license agreement. diff --git a/linux/drivers/media/dvb/dvb-usb/Kconfig b/linux/drivers/media/dvb/dvb-usb/Kconfig --- a/linux/drivers/media/dvb/dvb-usb/Kconfig +++ b/linux/drivers/media/dvb/dvb-usb/Kconfig @@ -315,3 +315,9 @@ config DVB_USB_CE6230 select MEDIA_TUNER_MXL5005S if !MEDIA_TUNER_CUSTOMISE help Say Y here to support the Intel CE6230 DVB-T USB2.0 receiver + +config DVB_USB_FRIIO + tristate "Friio ISDB-T USB2.0 Receiver support" + depends on DVB_USB + help + Say Y here to support the Japanese DTV receiver Friio. diff --git a/linux/drivers/media/dvb/dvb-usb/Makefile b/linux/drivers/media/dvb/dvb-usb/Makefile --- a/linux/drivers/media/dvb/dvb-usb/Makefile +++ b/linux/drivers/media/dvb/dvb-usb/Makefile @@ -79,6 +79,9 @@ obj-$(CONFIG_DVB_USB_CINERGY_T2) += dvb- dvb-usb-ce6230-objs = ce6230.o obj-$(CONFIG_DVB_USB_CE6230) += dvb-usb-ce6230.o +dvb-usb-friio-objs = friio.o friio-fe.o +obj-$(CONFIG_DVB_USB_FRIIO) += dvb-usb-friio.o + EXTRA_CFLAGS += -Idrivers/media/dvb/dvb-core/ -Idrivers/media/dvb/frontends/ # due to tuner-xc3028 EXTRA_CFLAGS += -Idrivers/media/common/tuners diff --git a/linux/drivers/media/dvb/dvb-usb/dvb-usb-ids.h b/linux/drivers/media/dvb/dvb-usb/dvb-usb-ids.h --- a/linux/drivers/media/dvb/dvb-usb/dvb-usb-ids.h +++ b/linux/drivers/media/dvb/dvb-usb/dvb-usb-ids.h @@ -59,6 +59,7 @@ #define USB_VID_YUAN 0x1164 #define USB_VID_XTENSIONS 0x1ae7 #define USB_VID_HUMAX_COEX 0x10b9 +#define USB_VID_774 0x7a69 /* Product IDs */ #define USB_PID_ADSTECH_USB2_COLD 0xa333 @@ -264,5 +265,6 @@ #define USB_PID_ELGATO_EYETV_DTT_Dlx 0x0020 #define USB_PID_DVB_T_USB_STICK_HIGH_SPEED_COLD 0x5000 #define USB_PID_DVB_T_USB_STICK_HIGH_SPEED_WARM 0x5001 +#define USB_PID_FRIIO_WHITE 0x0001 #endif diff --git a/linux/drivers/media/dvb/dvb-usb/friio-fe.c b/linux/drivers/media/dvb/dvb-usb/friio-fe.c new file mode 100644 --- /dev/null +++ b/linux/drivers/media/dvb/dvb-usb/friio-fe.c @@ -0,0 +1,483 @@ +/* DVB USB compliant Linux driver for the Friio USB2.0 ISDB-T receiver. + * + * Copyright (C) 2009 Akihiro Tsukada <tskd2@xxxxxxxxxxx> + * + * This module is based off the the gl861 and vp702x modules. + * + * This program is free software;
