V4L/DVB (12923): SAA7164: Add support for the NXP SAA7164 silicon
This patch adds support for all of the known shipping Hauppauge HVR-2200 and HVR-2250 boards. Digital TV ATSC/QAM and DVB-T is enabled at this time. Both tuners are supported. Volatiles and typedefs need rework, the rest is coding style compliant. Signed-off-by: Steven Toth <stoth@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
