Adding support to NPG Real DVB-T Hybrid PCI Express [cx23885]

Adding support to NPG Real DVB-T Hybrid PCI Express [cx23885]

[JLA]

I have a NPG Real DVB-T Hybrid PCI Express capture card, it is a
DVB/Analog PAL/FM hybrid card based around the cx23885 chip. I've
taken some pictures and checked the cx23885-cards files and it seems
most of the parts are there and I would like to add the card entry for
this model.
I can, if needed, probe the card with a logic analyzer.

ICs found on board:
 * Conexant CX23885-13Z
 * Intel CE6353 [Clone of Zarlink ZL10353 ?] (DVB-T Demodulator)
 * XCeive XC3028ACQ (RF tuner and analog IF demodulator) (Not in
tuner.h but on wiki?)
 * PI5V33OSQE 2-way (analog?) multiplexer

Windows driver ships with the `AV88PCIE.SYS` file and a somewhat
documented .inf file with it.

Any help on how should I proceed adding support for this card appreciated.

Best regards.

This card is supported by the cx23885 driver. Try

sudo modprobe cx23885 card=12

It's necessary to have the firmware for the XC3028. See 
https://www.linuxtv.org/wiki/index.php/Xceive_XC3028/XC2028#How_to_Obtain_the_Firmware
to obtain it or google it.
It runs for me and I can see the dvb tv with kaffeine.
