Some sort? It's GPL. The reason why it is stil based on the DVB-API of
2.6.12 is that there were too many API changes in the last time (especially
the PLL stuff) and with the upcomming S2 I currently don't see any
stabilisation in the near future. As the drivers works fine for the RB,
there's no need to waste time in continuously porting to the current API ;-)

Also, since no PCI card was using the chip at that time, I saw no sense in
actively porting it to the "official" tree or adding configurability...

First try with czap that you're actually getting a lock.

Maybe the parallel data output configuration is wrong and the data is
latched at the wrong edge. The value is in the inittab, adress 0x12. The
clock polarity is bit 0, so a change to 0xa1 would be worth a try.

I have the data sheet, but I don't know the current status of it. As NXP
still doesn't have it on their webpage, I assume it's on purpose.

BTW, just for the record, as I don't have the time to look at all DVB-cards
out there: If a DVB-S card with the Samsung DNBU10x12 tuners appears, the
stv0288-driver for it is already in the RB repository. Unfortunately, the
data sheet problem is the same...
