[linux-dvb] [Patch] FMD1216 band updates and control bytes

[Steve Toth]

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
