Hauppauge device HVR1955 and HVR1975 are old Cypress based
devices. When originally produced the demods were lacking
upstream drivers and the tuner was unsupported. Well fast
forward to now and the only thing missing is the identification
of si2177 tuner in the si2157 driver, as well as extension
of the pvrusb2 driver to accomodate i2c client devices
and multiple frontends. This series addresses what is necessary.

QAM/ATSC are fully tested and work, the DVB tuning
*should* work, but is completely untested. Both demod
drivers are compatible with multiple frontend usage due
to previous patches I've submitted, so things should
work in pvrusb2 as well.

Composite video input is tested. Unable to test s-video,
but it should work. Radio is fully untested. Analog TV is
a work in progress, coming soon.

HVR-1955:
- LGDT3306a ATSC/QAM demod
- si2177 tuner
- cx25840 decoder for analog tv/composite/s-video/audio

HVR-1975 dual-frontend:
- LGDT3306a ATSC/QAM demod
- si2168 DVB-C/T/T2 demod
- si2177 tuner
- cx25840 decoder for analog tv/composite/s-video/audio
