I haven't seen a NOVA-CI card yet, but from what I understand, there
must be some way to switch the CI functionality on and reroute the TS
through the CAM before it goes to the port of the SAA7146. This is
either done via I2C or one of the GPIO ports of the
SAA7146. Furthermore, there must be a way to talk to the CI chip and
through an implementation of the CI stack to the CAM. This could be
done via the debi port. So you will have to find out, how those two
tasks are accomplished and implement it in the driver.
