Yeasah Pell 70047f9cca V4L/DVB (3804): Tweak bandselect setup fox cx24123
*) Allow forcing the bandselect value with a module parameter to 
facilitate determining the correct bandselect frequencies.
*) Changes the bandselect frequency thresholds based on experiments 
with the above parameter in conjunction with the values in the spec.

Yeasah Pell 0e4558ab4a V4L/DVB (3803): Various correctness fixes to tuning.
*) Sets an additional tuner parameter (demodulator sample gain) that 
wasn't being set before.
*) Removes the low symbol rate tuner parameter tweaks in the previous 
patch -- it appears those tweaks are not necessary with the demodulator 
sample gain set correctly.
*) Cleanup and document the demodulator register initialization sequence.
*) Change set_fec routine to disable FEC auto scan when a specific code 
rate is selected.
*) Remove error message when reported FEC is invalid (which happens 
sometimes when the card has no signal)

Yeasah Pell dce1dfc2a5 V4L/DVB (3797): Always wait for diseqc queue to become ready before transmitting a diseqc message
The previous DISEQC code didn't wait, so it was unreliable

Mauro Carvalho Chehab caf970e09c V4L/DVB (3796): Add several debug messages to cx24123 code
Current debug messages at cx24123 are next to useless, since they don't
print the values sent/read to registers. With this patch, debug=1 will
show comprehensive messages. debug=2 will show also read/write operations
at I2C bus.

Vadim Catana a74b51fca9 V4L/DVB (3795): Fix for CX24123 & low symbol rates
- fixed the reception of channels with low symbol rates.
  ( The VGA1 and VGA2 offsets recommended by cx24109 docs for
  symbol rates from 1 to 5 MSps do not work. I changed them
  to values found experimentally. The charge pump current
  and FILTUNE voltage are now set to values recommended in
  the docs. This improves reception for symbol rates < 15 MSps.
  The values written in the SYSSymbolRate registers are calculated
  with better precision. )
		     
- fixed the cx24123_get_fec() function. It was returning the values
  for DCII mode.
- removed some unused variables

Vadim Catana 1c956a3ac0 DVB (2451): Add support for KWorld DVB-S 100, based on the same chips as Hauppauge
- Add support for KWorld DVB-S 100, based on the same chips as Hauppauge
Nova-S Plus (CX23883/CX24123/CX24109), without the Intersil ISL6421,
which is used for LNB control.
- LNB voltage and tone are controled by LNBDC and LNBTone bits from
register 0x29 of the CX24123 demodulator.
- The MO_GP0_IO register from CX23883 is used to turn LNB power on and off.
