I guess it would be a few weeks. In fact working on a similar but different device as of now.

I would suggest that you request AFA for docs. One needs to be under NDA or so.
(Though the docs are quite confusing)

Nothing weird, the chip is a bit flexible, with that flexibility it brings in a lot of troubles.
1) a second attempt at getting it right (got many things right, but some went wrong.
Works with just one device alone)
2) a RE driver for the AF9015 chip based, for a MASTER device based configuration.
3) an AF9015 driver which was done by AFA for one customer, who violated the NDA,
which is almost the source for 2 but very much specifically written for one tuner in mind.
According to AFA Tech, None of these they would like to have in kernel, since they
wouldn't be able to support newer configurations based on them.

Neither 3 will work. Lot of differences, what's common is very small.

At least digital should work for you (when done), though there will be the need for a
small stub additionally.
