I seriosly would prefer to move pll-stuff to a PLL-lib (which is done, 
thanks Gerd).

Maybe newer cards/boxes (with microtune tuners) are more complicated to 
abstract, but most of the pll-programmings currently written, can be 
moved to pll-lib.

E.g.:
I can removed about 200 lines from dvb-dibusb-fe-i2c.c when using the pll 
lib. Whereas 150 lines are just copies from other dvb-drivers.

Nearly the same for skystar2.c aka flexcop-fe-tuner.c

Just my 'Sempf',
Patrick.
