[media] Patch for cx18 module with added support of GoTView PCI DVD3 Hybrid tuner
I've got code which adds support of GoTView PCI DVD3 Hybrid tuner in
cx18 module and Andy Walls in ivtv mailing-list gave me some advice on
making a patch and sending it here. So here's the patch against
staging/2.6.37-rc1 branch (the tutorial recommends to include it as
plain text but if it's the case I can surely send as an attachment):
Several comments on the patch:
1. Both users on the official Gotview forum and support said that PCI
DVD3 is very similar to Yuan MPC718 card so the main part of code is
taken from Yuan configuration. Some users reported it to work properly.
2. Everything is being initialized correctly including analog, dvb,
radio and alsa parts. Analogue part and alsa virtual card is tested by
myself using original Gotview card.

Now, just one old bttv board uses the old RC5 raw decoding routines.
Its conversion to rc-core requires the generation of IRQ data for both
positive and negative transitions at the IRQ line. I'm not sure if
bttv driver supports it or if the transitions will be reliable enough.
So, due to the lack of hardware for testing, the better for now is to
just move the legacy routines to bttv driver, and wait for someone with
a Nebula Digi could help to port it to use also rc-core raw decoders.
