V4L/DVB (9010): Add support for SDMC DM1105 PCI chip
Add support for SDMC DM1105 PCI chip. There is a lot of cards based on it, like DvbWorld 2002 DVB-S , 2004 DVB-S2 Signed-off-by: Igor M. Liplianin <liplianin@me.by> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Support for cards based on the SDMC DM1105 PCI chip like
|
||||
DvbWorld 2002
|
||||
|
||||
Since these cards have no MPEG decoder onboard, they transmit
|
||||
only compressed MPEG data over the PCI bus, so you need
|
||||
an external software decoder to watch TV on your computer.
|
||||
|
||||
Say Y or M if you own such a device and want to use it.
