I went through the FMD1216 datasheet and updated the FMD PLL bands based
on the official document. The current values differ from the datasheet.
The existing dvb-pll.c values appear to work fine for the HVR1100, and
also work fine for many of the existing FMD tuner products so I don't
know whether this patch will be accepted or not. Some of the existing
bands are out (just a little) so tuning problems with the current values
may not be completely obvious. The current values are close, but not
accurate.
I submit this for comment/review.
If we feel the patch is appropriate I'll re-submit with sign-off.
Any testers who would like to try this out, I'd appreciate the feedback.
Regards,
Steve Toth
