After some efforts, i got to a stage where most things are done, except
for some small issues that i find a bit nasty.
Most of the nastiness can be seen in af901x_biu.c (i have added in the
comments near the relative areas)
The major issue that i face is that dvb-usb sees the Bus Interface as 2
objects (in the dual demod configuration), since there are 2 frontend's
being attached. (I don't see any clean way where i can do the BIU config
and or BIU specific access, which in fact happens only once)
Since i got a bit stuck up with frontend attach itself, temporarily left
out the firmware copy part.
Comments and thoughts would be interesting.
Thanks,
Manu
