[1/5] cx23855: add support for DVBSky T980C (no CI support)
Commit Message
This patch adds basic support for DVBSky T980C card. CI interface is not supported.
DVBSky T980C is a PCIe card with the following components:
- CX23885 PCIe bridge
- Si2168-A20 demodulator
- Si2158-A20 tuner
- CIMaX SP2 CI chip
The demodulator and tuner need firmware. They're the same as used with TT CT2-4650 CI:

Hello,
In hardware design, the CI host controller is wired with GPIO_0 of CX23885.
The GPIO_0 can be configed as the interrupt source.
Interrupt mode in PCIe driver is more faster than poll mode to detect CAM insert/remove operations etc.

Hi Max,
Thanks for the comments. I looked through the existing CIMaX driver
and came to the conclusion that it can be implemented either with the
IRQs or then just to rely on the polling like the USB devices have to
do. I don't think it's that important, as the user probably will not
add/remove the CAM that often. That being said, of course it would be
nice if we had a config option to choose if IRQ is supported or not.
If you have a patch for that, I'm happy to have it in.
Cheers,
-olli
