From: Antti Palosaari Date: Sat, 9 Jul 2011 02:36:07 +0000 (-0300) Subject: [media] Realtek RTL28xxU serie DVB USB interface driver X-Git-Tag: v3.4-rc1~110^2^2~190 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=831e0b718c8d28afe6c9c9c2fcaebb5a730201ed;p=karo-tx-linux.git [media] Realtek RTL28xxU serie DVB USB interface driver For now it supports only Realtek RTL2831U chip. RTL2831U is integrated DVB USB interface and DVB-T demod. DVB-T demod integrated to RTL2831U is Realtek RTL2830. Supported tuners are QT1010, MT2060 and MXL5005S.
