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:
