From: Antti Palosaari Date: Fri, 30 Mar 2012 12:10:08 +0000 (-0300) Subject: [media] Afatech AF9035 DVB USB driver X-Git-Tag: v3.5-rc5~26^2~519 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7f882c2e353ca58695e9b4fcc9e97a9d4cbcf273;p=platform%2Fkernel%2Flinux-3.10.git [media] Afatech AF9035 DVB USB driver AF9035 is integrated DVB USB interface and DVB-T demodulator. Integrated demodulator is AF9033 and its driver is attached runtime as a own module. Driver currently supports only one device, TerraTec Cinergy T Stick [0ccd:0093]. TerraTec Cinergy T Stick is based of Afatech AF9035 + Infineon TUA 9001 silicon tuner.
