Hi Olivier,

This patch need to be cross-tested before being included
into the main repository. The differences with last week's are :
- All the MT2060 handling code has been moved to a
"frontend" module.

Great.

- The tuner selection now relies on autodetection because
some manufacturers ( Yuan ) didn't bother to get USB IDs
different from the original DibCom demoboard.

They even are using the exact same windows-driver ;)

- The agc_tuner parameters are now set correctly.
- The spur avoidance algorithm is now disabled as default. I
tried to test it and I could not find any effect.
- The driver shall work with the following devices :
	- LITEON/Intuix S800/Toshiba DVB-T USB 2.0 Stick
	- MSI Digivox Mini SL ( as Philip Lawatsch found )
	- Grand DVB-T Pen USB 2.0 ( Please report PASS/FAIL )
	- Yuan PD300 DVB-T Mobility ( Please report PASS/FAIL )

Works.

!!! ATTENTION ACHTUNG ATENCIÓN !!!
It would be great if someone posessing a :
	"Hauppage WinTV-NOVA-T USB2" or "AVerMedia AverTV DVB-T USB
2.0 (A800)"
	checks whether this patch breaks the support of that device.
!!! ATTENTION ACHTUNG ATENCIÓN !!!

It doesn't after checking the Part/Rev register for 0x63 instead of != 0.

The fixture still have 2 problems :
- There is still no startup calibration. I am still trying
to figure it out.
- It gets into higher levels of code obfuscation due to the
the way the tuner is attached and the handling of the AGC
parameters customisation. Maybe someone with <em>The
Knowledge</em> can enhance that before  merging into <em>The
Main Tree</em>.

I would like to take care of your patch + I will modify the dib3000-driver to be able to set agc-parameters in its config-struct to be able to pass the best agc-settings for each of the board.

But before committing I will need your sign-off like:

Signed-off-by: Your Name <your@xxxxxxxxxxxxx>


best regards,
Patrick.
