This is used in conjunction with the STV0367 demodulator on
the STV0367-NIM-V1.0 NIM card which can be used with the STi
STB SoC's.
Barely associated to this specific patch, but for
dvb-pll.c, another thing that seems possible is to
convert the struct dvb_pll_desc uses to const and
change the "entries" fixed array size from 12 to []

It'd save a couple KB overall and remove ~5KB of data.

$ size drivers/media/dvb-frontends/dvb-pll.o*
   text      data     bss     dec     hex filename
   8520      1552    2120   12192    2fa0 drivers/media/dvb-frontends/dvb-pll.o.new

Peter,

Please add this patch on the next patch series you submit.
Ok will do, I've added this patch with a slightly updated commit message
to my series.

Joe - Can I add your signed-off-by?

Joe, nice optimization - thanks for that.

With regards to Peter's patch, is this a digital-only tuner, or is it
a hybrid tuner?

The 5th byte that you send to the THOMSON DTT7546X seems to resemble
the 'auxiliary byte' that gets set in tuner-simple.c

I'm not sure that dvb-pll is the right place for this tuner
definition, if this is the case.  Maybe this definition belongs in
tuner-simple instead, if the pattern matches better there.

Mauro, can we hold off on merging Peter's patch until we resolve this?

eek!  I mispelled my own email address.


With regards to Joe's patch - I'd like to see that merged.  ...and
here is my correctly spelled email address:
