I applied that too, but removed those register writes you added to
af9033 driver. Patch commit message was totally missing and I did a
*lot* of reverse-engineering in order to understand patch (actually all
these patches).
What I discovered, not sure if correct, but that patch updates IT9135 BX
chipset tuner related inittabs. Tuner config 60 and 61 was updated. I
take latest IT9135 windows driver binary from Hauppauge and extracted
inittab for tuner 60. It was just same as here. So I suspect these tabs
are just same than latest windows. Firmware is likely same too, but I
was too lazy to dump it out from windows driver and compare...
Also, what I suspect, the 0xfba8 register write I removed from that
patch, is some clock output provided by demod core. That is clock source
for tuner, right?
regards
Antti
