V4L/DVB (13000): add driver for 774 Friio White USB ISDB-T receiver
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. Signed-off-by: Akihiro Tsukada <tskd2@yahoo.co.jp> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
