I have been very busy with work today, and would have posted this earlier..

Here is the "cleaned up" patch for adding support for the Air2PC/Airstar2 HD5000
(LGDT3303 Frontend).


Changes to note from the last one I submitted are:

- I have tried to impliment the SNR for the LGDT3303 since it appears to be the
same formula for the 3302 and 3303..

- I have also tried to impliment the signal level based on information I was
provided by BBTI.. I am not sure if this is correct for the 3302, and it is a
unitless measure since I have no idea how it was calcualted..  I would need to
spend some time digging it spec sheets for both and see if I can come up with
something, but I only have the 3303 right now..

- The serial_mpeg value needed to be set to 0x04 for the demux to return data..
I am not sure as to why but the suggested value of 0x40 didn't return any data
from teh demux. (Could this have something to do with the wiring of the
frontend to the demux?)

- The frontend reset delay added to flexcop.c was reduced from 100 or 200ms to a
reasonable 1ms which gives adequate time for the 3303 to reset..

Also to note:

I have also put together a few liner patch to make the older version of the
DVICO FusionHDTV Gold3 work.. I have one that has a LGDT3302 and has a card id
of 18ac:d800 instead of 18ac:d820 (CX88_BOARD_DVICO_FUSIONHDTV_3_GOLD_T), but
appears to be the same.. I will validate this and post this seperately..
