[PATCH] Add support for SDMC DM1105 PCI chip

From:  "Igor M. Liplianin" <liplianin@tut.by>
To:  linux-dvb@linuxtv.org, video4linux-list@redhat.com, Mauro Carvalho Chehab <mchehab@infradead.org>
Subject:  [linux-dvb] [PATCH] Add support for SDMC DM1105 PCI chip
Date:  Sat, 13 Sep 2008 16:23:09 +0300
Message-ID:  <200809131623.10155.liplianin@tut.by>
Archive-link:  Article

The patch adds support for SDMC DM1105 PCI chip. There is a lot of
cards based on it, like DvbWorld 2002 DVB-S , 2004 DVB-S2
Source code prepaired to and already tested with cards, which have si2109, 
stv0288, cx24116 demods.  Currently enabled only stv0299, as other demods are 
not in a v4l-dvb main tree, but I will submit corresponded patches (si2109, 
stv0288) next time.

Best Regards
Igor M. Liplianin

+          Since these cards have no MPEG decoder onboard, they transmit
